Pin Spanners For Spindle Lock Nuts

These pin spanners are the recommended sizes for most angle grinders and rotary polishers. Some lock nuts have two sets of grip holes and either spanner would fit. Others have just one pair of holes, so it is important to check the pin size and distance apart. Angle grinders and polishers should have a direction of rotation which tightens the lock-nut. It is important on many rotary tools, such as bonded abrasive cutting discs, not to over-tighten the lock nut.
