Best Locking Pliers for Automotive Work
Locking pliers earn their place in an automotive toolbox because they clamp, hold, and twist when a regular wrench or screwdriver will not fit or will not grip. The right pair depends on whether you are dealing with rounded brake line fittings, seized hose clamps, stubborn exhaust bolts, or welding and fabrication work under the chassis.
Quick answer
The IRWIN VISE-GRIP Original Locking Pliers Set is the best overall pick for most automotive work because it covers the common jaw styles in one kit.

What Matters Most for This Category
For automotive work, jaw shape matters more than overall size. Curved jaws grab round stock like tie rods and exhaust pipe, straight jaws clamp flat brackets and sheet metal, and long-nose versions reach into tight engine bays. Look for hardened steel jaws, a pivot that does not loosen after repeated clamping, and a release lever you can trip with one gloved hand. Adjusting screw tension should feel smooth rather than gritty, because you will be resetting it constantly as you move between jobs.

Who Should Avoid the Top Pick
Skip locking pliers if your task needs precise torque, such as tightening brake caliper bolts or suspension hardware to spec. Locking pliers clamp and hold, but they do not measure torque, and using them on critical fasteners can round heads or leave you guessing at tightness. For those jobs, use a torque wrench and the correct socket.
Before You Buy
Check the jaw style against the fasteners you actually work on. Curved jaws suit round stock and rounded bolts, straight jaws suit flat brackets, and long-nose jaws suit confined spaces. Also confirm the length fits your available clearance, and make sure the release lever is reachable with gloves on.
FAQs
What size locking pliers are best for automotive work?
A 10-inch curved jaw pair handles most heavy clamping, while 6 to 7-inch models work better in tight engine bay spaces. Many mechanics keep both sizes on hand.
Can locking pliers remove rounded bolts?
Yes, curved jaw locking pliers are commonly used to grip and turn rounded bolt heads, especially on exhaust and suspension hardware. They work best when the jaws can bite into at least two flats.
Are VISE-GRIP pliers still good after the brand changes?
IRWIN continues to sell the VISE-GRIP Original line in the US, and owner feedback generally still rates the adjustment screw and jaw bite highly, though some users note quality varies by production batch.
Do I need a set or just one pair?
A set is more efficient if you do mixed automotive work, because curved, straight, and long-nose jaws each solve different problems. A single 10-inch curved jaw pair covers many jobs if you are buying just one.
Can locking pliers be used as a temporary clamp?
Yes, they are often used as temporary clamps for welding, gluing, or holding parts during assembly. Just avoid using them as a permanent substitute for a proper clamp under load.
How do I maintain locking pliers?
Keep the adjustment screw clean and lightly oiled, and avoid dropping them on the jaw tips. If the pivot loosens or the jaws round over, replace the pair rather than forcing it.
Our verdict
For most automotive work, the IRWIN VISE-GRIP Original 5-Piece Set offers the best balance of jaw variety, durability, and price. If you need maximum bite on rounded bolts, step up to the 10-inch curved jaw model, and if budget is the priority, the PITTSBURGH set covers the basics. Match the jaw style to your fasteners and locking pliers will earn their keep in the garage.
