Midwest Fasteners Zinc Plated Steel Grade 2 USS Pattern Flat Washers

Midwest Fasteners Grade 2 Zinc Plated Steel USS Pattern Flat Washers spread clamping load evenly under the head of a bolt, screw or nut while protecting the work surface from marring or over-torquing damage. Built from Grade 2 zinc plated steel in the standard USS outside-diameter profile, this family is available in washer sizes ranging from 3/16" x 1/4" x 9/16" up through 7/8" x 15/16" x 2-1/4", so shops and jobsites can match the exact washer to the bolt, screw or nut in hand.
