316 Hex Nut ø 12mm Stainless Steel Nylon Lock Nut ( Pack of 2 )

Feature:
When screwing the nuts onto the thread, the thread lock is plastically and elastically deformed.
The elastic deformation causes a radial frictional lock against the nuts being loosened.
The plastic thread lock is only effective when the nuts are fully screwed onto the male thread.
The screw length must be selected so that at least two full threads protrude from the nut.
