The BIOLOID Compatible Metal F2 Bracket is an aluminum replacement for the standard BIOLOID F2 bracket. 4 tapped holes on the sides of the frame make it easy to mount cable holders and 3D frames.
Compatible DYNAMIXEL Servos
This product is just the single metal bracket. This frame requires a Hub & Washer, an M3 * 10 bolt, and 4 M2*6 bolts (both bolts can be found in the Nut and Bolt Variety Pack). The AX-12A comes with this hardware, but the AX-18 does not.
