Beschreibung
Zusammenfassung:	An over torque prevention device includes a cap a cap configured for attachment to and removal from a threaded fastening member. The cap has a first portion shaped to engage a head of the threaded fastening member and a second portion having a surface feature shaped to receive a driver tool for applying a torque to rotate the cap and the threaded fastening member. The cap is formed of a material that has a lower shear strength than the material of the threaded fastening member. When a driver tool is used to engage the surface feature of the cap and apply an increasing torque, the surface feature or other portion of the cap deforms at a torque limit value such that further application of torque to the threaded fastening member is prevented.
