When sourcing supplies for your next project, look no further than Brazos Fasteners. We offer a large inventory of ASTM-F436 structural washers ready to ship to your office or job site.

High-Quality Structural Washers

Washers meeting the ASTM-F436 requirements are crafted to be stronger than standard hardware. Manufactured from higher-grade steel, they’re also heat-treated to boost their strength. Our ASTM-F436 flat washers offer key benefits:

  • Corrosion resistance: With durable constructions and coatings, F436 washers are less likely to break down from corrosion.
  • Greater surface bearing area: This helps disperse pressure more evenly under bolt heads and prevent surface damage.
  • Versatility: F436 washers are compatible with many fastener grades such as B7, B16, and L7.
