Washer M8

Washer M8 is a fastener element used together with screws and bolts to increase connection reliability and prevent self-loosening under vibrational loads.

Washer types

The large washer M8 is designed for fastening parts and structures when it is necessary to reduce pressure on the attached part. The heavy washer M8 per GOST can have a zinc-plated coating for corrosion protection against moisture exposure. The spring lock washer prevents self-loosening of screw and bolt connections under repeated loads.
