AB Tools Locking Pliers - 12" 300mm

Locking pliers, like these AB Tools models, provide a continuous, secure grip that stays in place without constant hand pressure, unlike standard pliers which require continuous squeezing.

You adjust the pressure using the knurled screw located at the base of the handles. Turn it clockwise to increase pressure and counter-clockwise to decrease it.

Yes, the strong tooth design is effective on various shapes, including hex, square, and round fasteners. The four-point pressure application helps grip damaged or rounded heads.

'Jumbo' typically refers to the size of the pliers, indicating they are a larger model, in this case, 12 inches (300mm), designed for heavier-duty tasks and larger fasteners.

Yes, the knurled adjustable screw is designed to provide fine control and grip even in oily conditions.

There is a quick-release lever, usually located on one of the handles, that you press to disengage the locking mechanism and open the jaws.

With proper care and regular lubrication, the strong rivet design and durable construction are made to last for extended use in demanding environments.

Ensure the jaws are properly positioned around the object. Adjust the knurled screw to increase tension before squeezing the handles. Check that the locking mechanism is clean and free of debris.

Clean the threads of the adjustment screw with a brush and apply a small amount of lubricant (e.g., WD-40 or light machine oil). Work the screw back and forth to loosen it.

Ensure the locking mechanism is fully released. If the jaws are still too narrow, check for any obstructions or damage in the jaw mechanism.

Ensure the teeth on the jaws are clean and sharp. Position the jaws to make maximum contact with the fastener head. For rounded fasteners, ensure a very firm grip and consider using the smallest possible jaw opening for maximum leverage.
