Pin Spanner Selection — Quick Reference
Pin spanners — SPECIALTY SPANNER with PROTRUDING PIN(S) that engage HOLE(S) in round nuts + bearing lock nuts. Workshop + automotive + machinery. Different from hook spanner (engages notch). Match PIN DIAMETER + spacing to lock nut.
| Pin Spanner Type | Best For |
|---|---|
| Single-Pin Spanner | Single-hole lock nut |
| Two-Pin Pin Spanner | Two-hole flange nuts |
| Adjustable Pin Spanner | Variable pin spacing |
| Face-Pin Spanner | Pins parallel to nut face |
| Side-Pin Spanner | Pins parallel to nut axis |
| Workshop Heavy-Duty | Industrial bearing + machinery |
| Match Nut Specification | Pin dia + hole spacing |
Critical: Match PIN diameter + SPACING precisely. Don't over-leverage — pin shear under heavy torque. Brands: Stahlwille, Gedore, Bahco. Companion: hook spanner wrenches, spanners, bearing housings, hand tools.
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, threaded lens retainers on machinery, spindle nuts on grinders and angle grinders, and pump and motor covers.
Styles
- Fixed pin spanners — sized to a specific pin spacing and pin diameter. Strongest for repeated use on one assembly.
- Adjustable pin spanners — one tool covers a range of pin spacings; the workshop default for occasional use across multiple machines.
- Pin face spanners (C-spanners) — combine a hooked end with a pin to engage round nuts that have one slot and one pin hole.

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: What is a pin face spanner (C-spanner)?
It combines a hooked end with a pin, for engaging round nuts that have one slot and one pin hole — a hybrid style for nuts that don't fit a pure pin-spanner or pure hook-spanner pattern.
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.
