Slip-joint pliers Knipex 86 05 150 Maximum nut size 2.7 cm

The Knipex 86 05 150 slip-joint pliers are a compact adjustable tightening tool made from chrome vanadium electric steel, forged and oil-hardened. With a length of 150 mm and a maximum nut size of 2.7 cm, these mini pliers wrench combine smooth jaws and a ratchet-type principle to allow damage-free installation and quick tightening or release of bolted connections. Their parallel, zero-backlash jaws and reliable hinge bolt catch deliver a solid grip for precision mechanics and everyday tasks.

Advantages

These pliers replace the need for separate metric and imperial spanners by offering an adjustable range up to the specified maximum size. Smooth jaws protect plated and chrome fittings from damage while parallel jaw geometry ensures a firm hold. The ratchet-like mechanism and lever transmission greater than 10:1 provide strong gripping power and allow quick operation. The tool is forged from chrome vanadium electric steel and oil-hardened for durability.

How to use

Adjust the jaw width by pressing the push button and sliding the movable jaw to the required position on the workpiece. Position the smooth parallel jaws on the nut or fitting, then use the pliers to grip and tighten or release the fastener. For repetitive tightening or loosening, use the ratchet-type action to operate quickly without realigning the tool on the workpiece. Use controlled force in line with the lever transmission to avoid overstressing the component.

Recommendations

Use these pliers on plated and chrome fittings without excessive force to prevent surface damage. Keep the push-button mechanism clean and lightly lubricated; inspect the hinge and jaws periodically for wear. Do not use the pliers as a hammer or on parts beyond the specified maximum size.
