How to choose
The right part depends on thread, load, surface and environment.
To choose a nut or washer, confirm diameter, pitch or thread, grade, finish, material and function in the assembly.
If there is vibration, load or corrosion, share the application to validate alternatives such as lock washer, flat washer, lock nut or stainless.
