Gold anodised 7075-T6 aluminium hub with two M4 grub screws to hold on to the shaft which will hold on much better than the typical single M3 grub screw. Four M3 tapped holes for mounting ~9mm apart from each other. Includes four 10mm M3 screws for mounting. Great for attaching wheels or a weapon arm to a gearmotor. We stock them in 4mm bore for our 22mm motors & Repeat Compacts and 6mm bore for 24mm motors such as Repeat Maxs & 37mm gearmotors. CAD files: 4mm STEP, 6mm STEP. Example robot below.
