Description
Monster Overview
Fix your project right the first time with F436 Structural Round Washers – Hot-Dip Galvanized (HDG) from Monster Bolts. Engineered and Made in the USA, these washers meet ASTM F436 structural-grade requirements and are designed for the demanding load conditions found in structural steel, bridge construction, heavy equipment, and industrial connections.
F436 structural round washers provide a larger bearing surface than standard flat washers, helping distribute load and protect structural members from bolt head or nut rotation. The HDG (hot-dip galvanized) coating offers a thick, durable zinc layer for excellent corrosion resistance in outdoor, marine, and exposed environments—all while remaining RoHS compliant.
