Best Locking Pliers 2026: Top Picks Tested for Grip and Durability

Introduction

A quality set of locking pliers is a must-have tool for any workshop. Whether you are gripping a rounded bolt, clamping metal for welding, or holding a stubborn fastener, a reliable pair of locking pliers can save the job. A low-quality pair, on the other hand, can slip, damage the workpiece, or fail under pressure.

We tested 18 brands of 10-inch locking pliers to find out which ones deliver the strongest grip, the best build quality, and the easiest release. The lineup includes budget options like Pittsburgh and Harden, mid-range picks like WorkPro and Durk, and premium contenders like Malco Eagle Grip, Irwin Vise Grip, and Knipex. Each pair was put through a series of controlled tests on soft metal, hardened steel, and hard tool steel to measure real-world performance.

How We Tested

To keep the testing fair, each pair of pliers was locked onto a grade two bolt with the adjustment screw tightened to 100 inch-pounds of torque. A torque wrench calibration tool measured the maximum torque before the pliers slipped. The same process was repeated on grade eight bolts and on 1/2-inch diameter socket extensions made of hard tool steel, with the adjustment screw torque increased to 180 inch-pounds for the hardest test.

We also measured the force required to release the lock on each pair, using a push-pull force meter with 60 inch-pounds of torque on the adjustment screw. Build quality, jaw pattern, and the smoothness of the adjustment screw were noted throughout.

Best Overall: Malco Eagle Grip

The Malco Eagle Grip locking pliers came out on top in every grip test. On the soft grade two bolt, they held on until 1,250 inch-pounds of torque, the best result of the entire lineup. They also led the front-teeth test at 222 inch-pounds and the hard tool steel test at just under 410 inch-pounds.

The patented power ring provides increased thread strength, and the pinned and braced upper jaw creates a superior bond between the jaw and the pliers body. The adjustment screw is the smoothest of any brand tested, which helps with clamp load. The teeth feature a diamond-shaped pattern that bites aggressively into the workpiece. At 536 grams, they are mid-weight for the category.

The Eagle Grips are made in the USA and cost $35. They do take a little more effort to unlock than some competitors, but that is a minor trade-off for the grip performance.

Best Value: Irwin Vise Grip

The Irwin Vise Grip is the original locking pliers brand, and it performed extremely well considering the $26 price tag. On the soft grade two bolt, the Irwin held on until 1,129 inch-pounds, finishing in second place. It also finished second in the front-teeth test at 169 inch-pounds and second on the hard tool steel test at 308.5 inch-pounds.

The curved jaw is designed for square, flat, round, or hex surfaces, and the pliers are constructed from high-grade heat-treated alloy steel. The adjustment screw moves freely, and the release lever is easy to operate at just 6.9 pounds of force. The diamond-shaped jaw pattern provides a secure bite. At 522 grams, the Irwin is one of the lighter options in the mid-range.

For anyone who wants strong performance without spending extra for the Eagle Grips, the Irwin Vise Grip is a great option.

Best All-Around: Craftsman

The Craftsman locking pliers performed well across all tests, with an average finish of fourth place. On the grade eight bolt test, the straight jaws allowed the bolt to be positioned very close to the fulcrum, which helped the Craftsman reach 772.5 inch-pounds, the third-best result in that test. On the hard tool steel test, it reached 284.8 inch-pounds, also third-best.

The Craftsman features one-hand operation with an easy release mechanism and multi-zone bilateral grips. The pliers are made with high-grade heat-treated alloy steel. The adjustment screw is not quite as smooth as the Klein Tools, but it is still workable. At 604 grams, the Craftsman is one of the heavier options tested.

At $20, the Craftsman is a solid all-around choice for general workshop use.

Durability and Build Quality

Build quality varied significantly across the 18 brands. The Pittsburgh pliers, at just $7, felt light at 438 grams and had a gritty adjustment screw. The body appeared to be pressed into position on the adjustment screw, and the pliers failed to register on the torque tester in the first two grip tests. The teeth were soft and experienced damage on the hard tool steel test.

The Harden pliers, at $9, included a weld that the Pittsburgh lacked, but the adjustment screw was still gritty. The Harden failed the hard tool steel test when the adjustment screw became misaligned with the connecting rod, a clear build quality issue.

At the other end of the spectrum, the Knipex pliers, made in Germany, had the most secure weld of any brand tested. However, the pliers began to bend under 180 inch-pounds of torque on the adjustment screw, and the jaw teeth experienced wear. The Knipex finished mid-pack in most tests.

The Milwaukee pliers, at $32 for two sets, featured forged alloy steel construction and very little wobble in the moving parts. They finished third on the soft bolt test at 987.3 inch-pounds but slipped to 373.6 inch-pounds on the grade eight bolt.

The Gedore pliers, at $48, had a secure weld and forged tempered jaws, but the adjustment screw did not move freely. The pliers began to bend under 180 inch-pounds of torque and failed to register on the tester.

Ease of Release

The force required to release the lock varied widely. The Harden pliers unlocked too easily at just 1.8 pounds of force, which could be a safety concern if the pliers release unexpectedly under load. The Klein Tools unlocked at 5.5 pounds, the Irwin at 6.9 pounds, and the Milwaukee at 7.7 pounds, all of which feel secure yet easy to operate.

The Stanley Proto required the most force at 20.3 pounds, followed by the Tekin at 18.8 pounds. The Tang Tools required 15.2 pounds, and the Durk required 14.7 pounds. The Malco Eagle Grip unlocked at 8.1 pounds, which is reasonable given the strong grip performance.

Buying Advice

If you need a pair of locking pliers for tough jobs where grip strength matters most, the Malco Eagle Grip is the clear winner. At $35, it is more expensive than most competitors, but it finished first in every grip test and is made in the USA.

For a more budget-friendly option, the Irwin Vise Grip at $26 offers nearly the same grip performance for significantly less money. It is the original locking pliers brand and remains a reliable choice.

The Craftsman at $20 is a great all-around set of locking pliers for general workshop use. It performs well across all tests and offers good value for the price.

Avoid the cheapest options like the Pittsburgh and Harden if you need reliable grip strength. They struggled in nearly every test and showed signs of poor build quality.

Conclusion

After testing 18 brands of 10-inch locking pliers, the Malco Eagle Grip stands out as the best overall choice for grip strength and durability. The Irwin Vise Grip offers excellent performance at a lower price, and the Craftsman is a solid all-around option. For any serious workshop, investing in a quality pair of locking pliers is worth the extra cost.
