Flat Washers
Stop bolt heads from digging in and joints from going soft. Kimball Midwest's selection of flat washers spread clamp load, protect surfaces and help you hold torque. Match SAE, USS or metric sizes, then pick Grade 5, Grade 8 or L9 for muscle. Go zinc or galvanized for weather, 18-8 or 316 for wet service, nylon or isoplastic for non-conductive builds.
