M4 x 0.7mm Nylock Nut (25 Pack) - ServoCity®

These M4 locknuts have a nylon insert that the threads of a mating screw must form threads in upon insertion.  The displaced nylon will continue to hold tension on the screw threads which act as a locking mechanism to prevent the screw from loosening under vibration.  While M4 is not a go-to in Actobotics®, they are sometimes necessary to have when utilizing parts from our metric build-system, goBILDA®.
