Titan flänsad metall lås mutter Bi-Hex M10x (1.00mm) (TILOCKNUTBH10FF)

A Flanged Lock Nut has an integral washer which serves to distribute the pressure of the Nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface.
It also uses a stamped metal insert which acts as a locking mechanism by deforming over the threads of the bolt.
the insert locks the Nut in two ways. First, it forces the bottom face of the screw threads against the top face of the Nut threads, increasing the friction between the two. Second, the insert applies a compressive force against the screw itself.
A good option where locking devices are required in high temperature applications. Machined from lightweight, highly corrosion resistant, grade 5 Titanium. Supplied here individually.
