ASTM F436 Washer
Get the ASME SF 436 Flat Washers and Lock Washers Dimensions Chart below
ASTM F436 Hardened Washers are used to give tightness to the joint, to prevent leakage and to distribute pressure under the head of nut or bolt. These are designed for general purpose like with bolts, nuts, studs and other threaded fasteners. ASTM F436 square washers are available in various sizes, forms. They cover pressure temperature ratings, materials, dimensions, tolerances etc.

ASTM F436 Flat Washer
ASTM F436 Lock washers prevents nuts and bolts from turning, slipping because of vibration and torque. This works by adding tension to a fastener assembly. These are thus used in various other industries. ASTM F436 Flat washers can be found in various sizes and it also has various dimensions and specifications. For smooth bearing surface, it is placed under the head of a bolt or nut. ASTM Bevel washers comes under square or rectangular shape in nominal sizes like ½ to 1 ½ inches with a beveled 1 to 6 ratios surface for use with American Standard. So basically, all these types of washers play an important role in each and every industry. There are might be many such steel industries who are manufacturing various steel products. But the one which is leading is regal sales corporation. As we introduce, ASTM F436 Round washers and many other products at reasonable rates.

Let’s understand what is F436, this is the material grade which is a flat washer that has a value ranging from 38 to 45 HRC. The ASTM F436 washers is used under bolt nuts and moves forward to increase the bearing area. This is used to protect the surfaces which was equally distributed while tightening bolt or screw and also prevent corrosion between steel screw and aluminium surface. Weathering steel ASTM F436 Type 3 washers are intended for structural use like bolts, nuts, studs and other threaded fasteners.
Whereas, structural washers are used in heavy duty building construction. These are perfectly coated for high corrosion resistance. ASTM F436 structural washers have dimensions comparable to USS plain washer but with a smaller outside diameter.
