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.
