Pin Spanners at AIMS — Trax, Maxigear & Super
Pin spanners are specialty wrenches with one or two protruding pins that engage holes in the face of a round nut, locknut or threaded cover. They're the right tool for assemblies that don't expose a hex flat — bearing locknuts on shafts, spindle nuts, and pump and motor covers. AIMS Industrial stocks pin spanners from Trax, Maxigear and Super.

Fixed or adjustable?
- Fixed pin spanners are sized to a specific pin spacing and diameter, and are the strongest choice for repeated use on one assembly.
- Adjustable pin spanners cover a range of pin spacings with one tool. They're the workshop default for occasional use across multiple machines.
Match the pin diameter and hole spacing to the nut, and don't over-leverage: pins can shear under heavy torque. Not sure which one you need? Contact our team or call (02) 9773 0122.
People Also Ask — Pin Spanners
Q: What's the difference between a pin spanner and a hook spanner?
A pin spanner engages one or two holes in the face of a round nut or cover. A hook spanner engages a notch or slot instead of a hole. They're not interchangeable — match the tool to the nut's engagement feature.
Q: Fixed or adjustable pin spanner?
Fixed pin spanners are sized to one specific pin spacing and diameter, and are the strongest choice for repeated use on the same assembly. Adjustable pin spanners cover a range of pin spacings in one tool — the workshop default for occasional use across multiple machines.
Q: Can I over-torque a pin spanner?
Don't over-leverage — the pins can shear under heavy torque if you apply excessive force. Match the pin diameter and spacing precisely to the nut and use controlled force rather than extending the handle for extra leverage.
