Unique head release design-Only the Vlier Torque Thumb Screw uses a spring-controlled ball-checkin the head release mechanism which is perpendicular to the screw axis, assuring accurate end force every time with long life and no wobble.

Head design prevents chips, dirt, etc. from reaching the working parts. A retaining ring secures the knurled ring in place, but permits complete disassembly in seconds.
Vlier Torque Thumb Screws are specially designed for positive repeatable end force and are ideal for applications where controlled forces are required. When the factory pre-set torque/force is reached, the head of the torque thumb screw turns freely, preventing overtightening which could cause the workpiece to deform or distort. Backing-off action is positive, speeding unloading. TORQUE-LIMITING DEVICES- The simple, fool-proof principle used in Vlier Torque Thumb Screws has been adapted to many designs. Steel with black oxide finish.
