Vice grips are locking pliers, and their toothed jaws are designed to bite. That bite can leave dents, scratches or distorted edges, especially on finished, soft or reusable parts. The safest approach is to avoid locking pliers when a correctly sized wrench, clamp or other purpose-built tool can do the job. If vice grips are appropriate, match the jaw shape to the part, use only enough adjustment to hold it, and test any protective barrier on scrap or a concealed area first.
No setting makes locking pliers damage-proof. The steps below reduce risk; they cannot guarantee a mark-free result on every material or finish.

Why vice grips leave marks
Locking pliers hold by concentrating force at the jaw faces. Common vice-grip jaws have teeth that prevent a part from pulling free while you apply hand force or torque. The same teeth can gouge paint, flatten tubing, raise burrs on metal or leave visible impressions in a polished surface.
An educational tool-use guide warns that “the teeth in the jaws tend to damage the object on which they are clamped.” It specifically cautions against using vise-grip pliers on reusable nuts, bolts, tube fittings and similar objects. Treat that warning as a first decision point, not as a minor caveat.

When a mark is unacceptable
- Do not make vice grips your default substitute for a correctly sized wrench on a reusable fastener.
- Be especially cautious with painted, plated, polished, soft or cosmetically visible surfaces.
- Assume a thin-wall tube, threaded fitting or precision edge can be permanently deformed by a toothed jaw.
- If the part must be reused and you cannot tolerate a jaw impression, choose another tool or redesign the setup so the locking pliers never contact the finished area.
Decide whether locking pliers are the right tool
Before adjusting the screw, identify what the tool must do. “Hold this part while I work” is a clamping task; “turn this seized object” is a gripping and torque task. A jaw style that works for one may be a poor choice for the other.
Use a different tool first when the part is reusable
A six-point socket or correctly sized wrench spreads contact around a fastener without biting into its outside surfaces. A conventional clamp with broad, smooth faces is usually preferable for holding a finished panel or glued assembly. For tubing and fittings, use the wrench or fitting tool specified for that connection. These choices preserve the workpiece instead of relying on a toothed grip.
Locking pliers can be reasonable for sacrificial or hidden areas
Vice grips make sense when the contacted area will be cut away, discarded, welded over, or hidden, and when ordinary pliers cannot maintain enough hold. They can also serve as a temporary fixture while you position parts. Even then, keep the force and contact area as controlled as the job allows.

| Configuration | Documented use or feature | Damage-control implication |
|---|---|---|
| Curved-jaw locking pliers | IRWIN describes curved jaws for gripping and applying torque to round pipes, square or hex bolts and other varied shapes. | Useful when the part’s shape requires a surrounding grip, but the toothed contact can still mark the surface. |
| Swivel-pad locking pliers | CHANNELLOCK says its swivel-pad jaw design secures tough clamps while evenly dispersing force and reducing material damage. | A sensible option for clamping surfaces where distributing pressure is more important than biting into a fastener. |
The swivel-pad description is a damage-reduction claim, not a promise that every material will remain unmarked. Select pads that actually seat on the workpiece; a small or misaligned pad can still concentrate force.
Curved jaws for gripping and torque
IRWIN describes its adjustment screw as a way to set the jaw opening and pressure. Its product description says the tool “Tightens to draw material closer together for tighter grip. Loosens to provide controlled release.” Curved jaws can conform better to round or irregular shapes than flat jaws, but they remain a biting tool. If you are turning a reusable nut or fitting, use the proper wrench instead.
Swivel pads for clamping
A swivel-pad design lets the contact face align more closely with the surface as the jaws close. CHANNELLOCK says this distributes force evenly and reduces material damage. That makes this style worth considering for a temporary clamp, especially when a toothed curved jaw would contact a broad finished surface. It does not establish a universal safe pressure, approved material barrier or zero-damage guarantee.

- Clean both contact areas. Remove chips, grit, loose rust and dried adhesive. A particle trapped between a jaw and a finish can act like an abrasive point when pressure is applied.
- Inspect the jaws. Look for damaged teeth, sharp burrs, embedded metal or a bent pad. A damaged face can create a high-pressure spot.
- Choose the least visible contact zone. If the part has an unfinished edge, an interior flange or a section that will be trimmed, place the jaws there rather than on the show surface.
- Align the tool with the load. Keep the jaws square to the part and place the intended load through the jaw faces. An angled setup can make the tool slide or twist, encouraging you to tighten it harder.
- Plan the release. Make sure you can reach the release mechanism without placing fingers where the handles or workpiece may move.
Using a barrier between jaw and workpiece
A piece of cloth, rubber, leather or a commercial soft-jaw cover may reduce direct tooth contact, but the retrieved manufacturer sources do not identify one universal approved barrier or thickness. Treat a barrier as an experiment, not insurance.
- Use a clean, thin, non-shedding layer that lies flat. Folds can create pressure ridges.
- Check that the layer cannot slide out when the jaws are loaded.
- Remember that a thick or compressible barrier changes the jaw opening and may make the grip less predictable.
- Try the complete setup on scrap or a concealed area when the finish matters.
- Stop if the barrier slips, bunches, stains the surface or allows the part to rotate.
Testing on scrap is cautious practice, not a sourced requirement and not proof that the production surface is safe.
Adjust vice grips for the minimum reliable hold
The adjustment screw controls how tightly the jaws close. Start loose, seat the tool, and increase pressure only until the part stays put for the intended task. Extra force increases the chance of a tooth impression without necessarily improving control.

- Open the jaws. Back off the adjustment enough to place the tool around the part without scraping it into position.
- Seat the jaws or pads. Confirm that both sides contact where you planned. Do not let one tooth, pad edge or jaw corner carry the entire load.
- Set a light initial tension. Use the adjustment screw to bring the jaws close while the tool is still easy to reposition.
- Close the handles and assess the hold. The locking action should secure the part without crushing, bowing or visibly imprinting it. If the handles will not lock, adjust in small increments rather than making a large change.
- Apply only the task force. For a stationary clamp, the part should resist ordinary hand movement. For turning work, increase control through your body position and a better-fitting jaw before simply tightening harder.
- Recheck after loading. Apply a gentle trial force in the direction you will actually work. If the tool shifts, release it, correct alignment or choose a different tool; do not assume more pressure is the only solution.
This conservative procedure is an inference from the adjustable screw and the documented risk of tooth damage. Neither IRWIN nor the educational guidance establishes a universal screw setting that is safe for every material.

Holding a part without marring it
For temporary positioning
Use the smallest jaw contact that gives stable positioning, and support the part so the vice grips are not carrying its full weight. A second clamp, a fixture or a workbench stop may let you reduce jaw pressure. Keep the tool out of the path of a saw, grinder or drill, and do not use a locking plier as a substitute for a fixture when the setup will be struck repeatedly.
For cutting, drilling or filing
Mark the intended contact zone before clamping. Keep chips from packing into the teeth, and pause if vibration causes the part to creep. If the surface begins to show a crescent, bright spot or crushed edge, release the tool and change the setup; continuing usually deepens the mark.
For holding tubing or thin material
Assume that a toothed jaw can flatten or ovalize thin walls. Use broad, smooth support where possible, and place pressure over a reinforced section rather than an unsupported span. If the tube is a reusable fitting or part of a sealed system, follow the fitting manufacturer’s specified tool instead of locking pliers.

Turning an object with vice grips
Turning requires more caution than static clamping because torque can make the jaws climb, twist or bite deeper. IRWIN’s curved-jaw description covers gripping and torqueing varied shapes, but that capability does not override the warning about reusable fasteners and fittings.

- Verify that the object is expendable, hidden or otherwise suitable for toothed contact.
- Seat the jaws as close as practical to the section you intend to turn, with the tool aligned to the turning plane.
- Use a short, controlled movement first. Do not add a long cheater bar unless the tool and workpiece are specifically rated for that load.
- Watch for jaw rotation, surface movement or a developing indentation. Release and reset if any appears.
- If the object will not move with controlled force, stop and use a penetrating treatment, heat procedure or purpose-built extractor appropriate to the material and task instead of escalating clamp pressure blindly.
Release the tool without adding damage
Support the workpiece before unlocking. Use the release mechanism built into your model and keep your fingers clear of the handles and any part that may spring or shift. Once open, lift the jaws away rather than dragging them across the finish. Inspect the contact area immediately; a fresh mark is easier to address before the part is returned to service.
Do not twist the adjustment screw while the tool is still carrying an unpredictable load unless the tool’s instructions specifically allow that procedure. A controlled release and a new setup are safer than forcing a stuck mechanism.
What to do when marks appear
- A shallow tooth impression: Stop the operation, clean the area and determine whether the surface is merely compressed or actually cut. Reset on a sacrificial zone or change tools.
- A scratch running across the finish: Look for grit, a burr or a sliding jaw. Clean and inspect before trying again; adding pressure will not remove the abrasive cause.
- A flattened tube or bent edge: Release immediately. The part may no longer seal, fit or carry load correctly, so assess it against the relevant repair or replacement standard.
- The tool slips despite tight adjustment: Check jaw shape, alignment and contact area. A swivel-pad clamp or a purpose-built fixture may distribute force better than a tighter toothed bite.
- The barrier moves or leaves residue: Remove it and test a cleaner, thinner option on scrap, or abandon the barrier approach. A slipping layer can be more damaging than direct, controlled contact.
A repeatable low-damage workflow
For jobs where locking pliers remain appropriate, use this checklist:
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →- Classify the part as reusable, finished, soft, hidden or sacrificial.
- Choose a wrench, clamp or fixture instead if the part cannot tolerate toothed contact.
- Select curved jaws for a shape that needs gripping or torque, or swivel pads when broad clamping pressure is the priority.
- Clean and inspect the contact faces.
- Pick a concealed or expendable contact zone.
- Test a carefully fitted barrier on scrap or a hidden area if you decide to use one.
- Adjust from loose to secure in small increments.
- Load the tool gently in the direction of work and watch for movement or imprinting.
- Stop and change the setup at the first sign of slipping, crushing or marking.
- Release with the workpiece supported, then inspect the contact area.
Limits you should keep in mind
The available manufacturer descriptions establish adjustable grip, curved-jaw versatility and a swivel-pad design intended to distribute force and reduce material damage. They do not establish a universal protective material, pressure setting, test protocol or zero-damage result. Material hardness, coating thickness, jaw condition, alignment and applied load all affect the outcome.
That is why “use less force” is useful guidance but not a guarantee. The practical goal is controlled contact: select a tool that fits the task, put it on the least vulnerable area, apply only the force needed to hold or turn the part, and verify the setup before committing to the operation.
