ASTM F 436:2024 Inch Series Washer

ASTM F 436:2024 Inch Series Square Taper and Clipped Square Taper Washer is used for angular compensation and high-strength bearing in inch-series structural connections. It can be paired with channels, I-beams, or other sloped structural members so that the fastener works against a corrected bearing surface.

The product is suitable for bridges, building steel structures, heavy supports, engineering equipment, and projects requiring high-strength bolted connections. The clipped or square taper form improves load transfer and reduces the risk of bolt bending and localized indentation.

Hardened steel, galvanized, or other corrosion-protection versions can be selected according to project specifications to meet requirements for outdoor exposure, heavy loads, and long-term structural safety.
