These 7mm Hex Adapters allow you to attach 7mm hex drive wheels to 1/4" drive shafts. Simply insert a 1/4" shaft (D-shafting is recommended) into the adapter and tighten the set-screws.

Hex is 3mm deep. Overall length of the entire hub is 22mm. 1/4" bore for common D-shafting used in pullers and our Mini pulling sled. Includes m4 set screws and m3x6 button head screws to secure the wheel to the hub (running a washer would be optionally recommended depending on wheel).

You could use these hubs to mount standard 1/24 or 1/28 scale crawler tires/wheels to 1/4" axles.

Includes
2x 7mm hex hub w/ set screws and wheel screw
