Genuine DeWalt 401680-00 spanner (pin) wrench — a two-pin tool designed to engage the holes in the grinder’s flange nut so you can quickly loosen or tighten the wheel on 115 mm angle grinders.

The wrench is a simple, heavy-duty steel pin wrench with two nodules that line up with the flange nut; overall length is approximately 194 mm.

Compatible with a wide range of DeWalt and Black & Decker grinders — example models include D28110, DC411, DW402, DW818, DW821, DW831 and DW840 — so it’s a direct-fit replacement for the listed angle-grinder types.

Supplied as the single genuine DeWalt 401680-00 wrench, it restores proper wheel removal/installation and makes safe wheel changes quick and straightforward.
