Auniwaig C Hook Wrench 28-32mm

This forged steel hook wrench fits round nuts from 28 to 32 millimetres and measures 14.4 centimetres overall. The unibody construction uses 45 steel for high hardness and a long service life. Nickel-plated electrophoresis coating protects the surface. It is intended for technicians who service ER collet chucks and similar threaded rings.

Unibody design with hanging hole

The single-piece shape eliminates joint play and reduces the risk of damaging the shaft, nut or housing during tightening. A hole at the handle end allows wall storage and easy portability. Two colour variants, black and red, are supplied so users can colour-code tools if desired. No additional accessories or software are included.

For ER collet nuts 28-32mm

Suitable for machinists and maintenance staff who regularly adjust round ER chuck nuts in the stated size range. Not suited for buyers who need a wrench for smaller or larger nuts, or for those who require a torque-limiting tool. Builders needing a double-ended or adjustable hook spanner should look elsewhere.

Questions about this item

Will the 45 # steel jaws need replacement after repeated use on 28-32mm ER collet nuts?

The forged 45 # steel construction provides high hardness for long service life; no scheduled jaw replacement is required under normal hand-tightening torque.

What stops me from applying more leverage on the 14.4cm handle when a nut is seized?

The short 14.4cm overall length limits mechanical advantage, so excessive force can deform the unibody hook before the nut breaks free.

Does the nickel-plated electrophoresis finish stay cool during continuous tightening cycles?

The tool has no moving parts or power source, so it generates no heat; the metal simply reaches ambient temperature during all-day use.
