The requirements for hardened washers with diameters ranging from 1/4" to 4" inclusive are covered by the standard of the F436 Washer Material Grade. The ASTM F436 Material is essentially a set of heat-treated washers for both general-purpose applications and structural use. The F436 Material Grade washers work well with other fasteners that meet the requirements of the specification, such as the A325 and A490 structural bolts.
Table of Content
Additionally, the F436 Material Grade Washers can be used with bolts like A449, A354, A193, A320, and F1554 whenever specified. Rockwell hardness values for flat washers in the F436 Material Grade range from 38 to 45 HRC. These washers can either be hot-dipped galvanised or have a plain finish.
To improve the bearing area, the ASTM F436 Flat Hardened Washer is placed beneath the bolt nuts and head. Additionally, it provides hardness to allow rotation of the bolt or nut without distorting the bearing's surface. In order to prevent leakage, tighten a joint, and most importantly, distribute pressure under a nut's or bolt's head, F436 Washer Material Grade are used with bolts and nuts.
