ASTM F436 Flat Washer

ASTM F436 flat washers in plain finish are hardened, load-distributing washers designed for use in structural and high-strength bolting applications. Ideal for pairing with A325 and A490 bolts, these washers help prevent embedding, reduce surface damage, and ensure proper load distribution.

Description

ASTM F436 flat washers are hardened steel washers engineered for use in structural connections where high-strength bolts are required. These washers are commonly used with ASTM A325 and A490 bolts to distribute load, prevent galling, and protect connection surfaces.

The plain finish provides a cost-effective solution for applications where corrosion resistance is not a primary concern or where additional coatings will be applied post-installation.
