Midwest Fasteners Zinc Plated Grade 2 Steel Split Lock Washer

Midwest Fasteners Zinc Plated Grade 2 Steel Split Lock Washer

The Midwest Fasteners Split Lock Washer family pairs a Grade 2 steel body with a zinc plated finish, giving contractors and maintenance techs a dependable, correctly sized part for everyday bolted assemblies. This family spans sizes from #6 x 1/8" x 1/4" and #8 x 5/32" x 9/32" up through 7/16" x 25/32", 1/2" x 7/8", 9/16" x 31/32", 7/8" x 1-15/32", and 1" x 1-5/8", so the right washer can be matched to the bolt or screw diameter in use.
