T-Track Cams

T-Track cams have a 3/8″ hole and a deep recess to allow a 3/8″ bolt and nut to secure the hub down to an aluminum T-Track. In use a 9/16″ socket wrench or fixed offset wrench loosens the nut with just a half-turn, then after sliding the cam up to the workpiece another half-turn re-tightens the nut.
