High accuracy and clamping force are provided with thrust ball bearings. MEGA ER Nuts are ideal for solid carbide drills and reamers. They have a slot-free outer diameter, which increases the rigidity of the nut itself. The one-way clutch of the MEGA Wrench tightens the nut securely and easily by its ratchet function.
