150 mm Safety Wire Twist Pliers

When critical fasteners must stay put, safety wire is the answer — and the right tool makes the difference between a neat, secure twist and a frustrating fight with bare fingers or makeshift pliers.

This Teng Tools 150 mm plier is purpose-built for wire twisting. A central pull-knob drives the rotating mechanism: clamp the wire in the jaws, pull the knob back, and the body spins to deliver even, consistent twists every time. There is no guesswork and no hand fatigue from trying to roll conventional pliers between your palms.

At 150 mm overall and weighing 253 g, the tool is compact enough to reach into tight engine bays, behind brake assemblies, and around airframe access panels where longer alternatives simply will not fit. The shorter profile also gives you finer control over twist pitch, helping you avoid the over-rotation that snaps wire prematurely.

Part of the Teng Tools Service Tools range, this plier is designed for technicians who perform lock-wire procedures on aircraft, race vehicles, heavy equipment, and any application where fastener security is non-negotiable. Whether you are wiring exhaust manifold studs on a track car or securing avionics panel screws to regulatory standards, the pull-knob mechanism delivers the repeatable results professionals demand.

Pair it with your preferred spool of stainless safety wire and keep it in your toolbox or flight bag so it is always within reach when the job calls for proper fastener retention.
