- Lock-Wheel with special patent thread ensures a secure hold. It can be tightened safely by hand without tools.
- The 2-hole mount (suitable for 2 mm Allen key or screwdriver) allows a firmer tightening torque of the Lock-Wheel with maximum hold.
- Undetachable hold due to grub screw with tapered cap and slot 2.5 x 5 mm made of stainless steel. Simply unscrew the set screw again to unscrew the Lock-Wheel; the thread remains functional and cuts itself “”free”” again through the Lock-Wheel.
