Metric Lock Washer, External
Toothed lock washer products
1.Descripition
A Toothed Lock Washer, also known as a Serrated Washer or Star
Washer, has serrations that extend radially inward and/or outward
to bite into the bearing surface. This type of washer is especially
effective as a Lock Washer when used with a soft substrate, such as
aluminium or plastic but can still resist rotation more than a
Plain Washer on hard surfaces as the tension between washer and the
surface is applied over a much smaller area (the teeth). There are
four types: Internal Toothed Washers, External Toothed Washers,
Combination Toothed Washers, and Countersunk Toothed Washers. The
internal style have the serrations along the inner diameter of the
washer, which makes them more aesthetically pleasing. The external
style have the serrations around the outer diameter, which provides
better holding power, because of the greater circumference. The
combination style has serrations about both diameters, for maximum
holding power. The countersunk style is designed to be used with
flat-head screws.A Toothed Lock Washer, also known as a Serrated
