The 2.0mm WERA Hex-Plus L-Key is an allen wrench that fits any button head or flat M3 screw, such as those used to attach the gearbox to the motor body in the UltraPlanetary Gearbox Kit & HD Hex Motor, or those used to fasten slides to extrusion in the 15mm Linear Motion Kit V2. Long-arm hex keys offer extended reach for enhanced leverage and maximum torque, beveled ends for easy insertion into fastener head, and a ball-end design for working in difficult installation situations.

WERA tools are extremely high quality and made in Germany.
