9/16" Stainless Steel Shakeproof External Serrated Lock Washer ASME B18.21.1 M3-M24


Description


Stainless Steel external tooth lock washers are used under bolt heads or nuts to increase the hold of the fastener. They can be manufactured of 18-8 or 400 series stainless steel. External tooth lock washers have teeth on the outer dimension of the washer creating a ratchet action by biting into the nut or screw head and the surface it contacts. Dimensional specifications are governed by ASME B18.21.1. Stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resistance, such as chemical and food processing equipment.


Lock washers create tension by “locking” the bolt or screw into the workpiece’s threaded hole. Unlike flat washers, they have serrations on the washer body to prevent rotation and provide a more secure connection than flat washers. These washers are frequently used in high-vibration environments to prevent the loosening of the fastener assembly.

Note


Use external tooth lock washers when you need maximum holding power in a washer. Team them up with fasteners having heads large enough to make contact with the washer teeth. Examples include: round head, pan head and binding head. Zinc plating, retards the corrosion rate in a normal atmosphere.
