Screws Stripping off

Stripping off occurs when tension generated by assembly torque is higher than nut shear strength. Consequently we notice that screw turns into the hole even reducing torque value.

Parameters like torque, engagement, hole diameter, friction… could affect stripping torque values. In these cases we recmmend to verify materials, design and final requirments to determine the best solution and assembly parameters.

The following figure shows the distribution of plastic created by REMFORM^® screw. The larger contact surface with the thread flanks provides better resistance to stripping.
