Security Fasteners
Re-usable security nuts combine consistent prevailing torque capabilities with tamper-resistant outer geometries to balance high security with maintenance accessibility. They feature unconventional external profiles—such as pentagonal, seven-sided, or wave patterns—that strictly require bespoke socket drivers to manipulate. Unlike breakaway shear nuts, their robust metallurgical construction allows them to endure multiple tensioning cycles without compromising thread integrity or clamping force. These fasteners are critical in securing railway infrastructure, military assets, and public utility fixtures where periodic authorized servicing is mandatory.
