Nylstop – Self-locking nuts

For a better engagement between bolt and nut, Nylstop self-locking nuts ensure a tight, anti-vibration grip by means of the nylon ring which is deformed around bolt threads. The products are available in steel property class 8 and class 10, as well as stainless steel A2 and A4 and fulfill a variety of application requirements. Nylstop nuts can be used in any industrial applications with wide diameter range from 4 mm up to 33 mm.

We also offer you a one-piece self-locking bearing nut, which is a great combination from standard locking nut and bearing nuts. Reduce pre-working time and related costs.
