Flat Washers (Through-Hardened)
A through-hardened (thru-hardened) washer is a standard flat washer that is specially hardened for use with Grade 5, Grade 8, and A193-B7 bolts. It helps increase the bearing surface of the bolt by spreading the force out radially. These products only come in one grade and are either plain or zinc/yellow. You may also consider looking at F436 structural washers (designed for A325 and A490 bolts).
