Available in carbon and stainless steel and thread sizes ranging from M6 to M16 (metric coarse thread), a new locknut fastener from bigHead features a robust, all-metal construction with a spring stainless steel locking insert to nut that permits extraction and reinsertion of the fixing bolt without affecting locking performance.
The fastener's locking efficiency is as effective as any other self-locking nut design, but it is easier fit, thanks to the low installation torque. Installation methods can include nut-runners and power tools.
