Conelock Nuts - Flanged

Conelock Nuts are one piece, all-metal prevailing torque hex nuts and have threads at the top of the nut that are imperfect and cause interference to allow them to lock and not vibrate and become loose. The Conelock Nut has a washer like flange built in. This enables you to save time on installation, as you don't require a separate flat washer and provides a load bearing surface.
