Malleable Plain Iron Square Beveled Washers
What are malleable plain iron square beveled washers? Malleable plain iron square beveled washers are the standard structural beveled washer, made from tough malleable iron with an angled face. The bevel compensates for the sloped flanges of I-beams and channels, letting the nut or bolt head bear on a level surface in most structural connections.

Why malleable iron for beveled washers?
Malleable iron is strong yet tough enough to resist cracking under structural loads, which is why it is the traditional material for beveled washers used with American standard beams and channels. The 1 to 6 taper corrects for the sloped inner flange so the fastener bears squarely and holds preload. Malleable iron beveled washers suit most structural bolting, while high-strength A325 and A490 joints call for a hardened F436 beveled washer instead. The plain finish is economical for dry or coated structural work; for outdoor exposure, choose galvanized, and for corrosion resistance choose stainless.
Why choose malleable plain iron square beveled washers
- Structural standard: the traditional beveled washer for beams and channels.
- Tough: malleable iron resists cracking under load.
- Levels the bearing: 1 to 6 taper corrects sloped flanges.
- Economical: plain finish for dry or coated structural work.
