For example, if your nut measures 40mm across, choose the 38–42 variant.

Angle grinder spindle lock rings are one of the most common uses for a C spanner hook wrench. Check your grinder's lock ring diameter — most 4–5 inch grinders use rings in the 38–52mm range, while larger 7–9 inch models may require the 55–72mm range.

A pin spanner uses one or two round pins that fit into holes drilled into the nut face. The correct choice depends entirely on the nut design — slotted edge nuts require a hook spanner; hole-pattern nuts require a pin spanner. Check your nut type before purchasing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan this wrench be used on motorcycle or bicycle wheel hub bearing nuts?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes, provided the hub bearing retaining nut has a slotted outer edge and its diameter falls within one of the available size ranges.
