Description

1-1/8" Conquest F436 Flat Washer – Hot Dip Galvanized

This 1-1/8" structural washer is hot dip galvanized for long-lasting rust resistance in high-moisture and outdoor environments. Its flat, hardened body meets ASTM F436 specifications for use with A325 and A490 bolts. Built to resist distortion under high torque, it maintains bolt tension and protects critical surfaces. Compatible with galvanized coarse or fine thread bolts.

Use only with hot dip galvanized bolts and nuts to maintain thread fit and corrosion protection.

1-1/8" HDG Washer for Infrastructure and Heavy Framing

This washer is ideal for bridge beams, tower bases, or framing in exposed outdoor settings. It provides uniform pressure and helps prevent bolt head embedment into structural materials. The hot dip galvanized finish extends product life even in harsh conditions. A reliable part of any structural fastening system.

  • 316 Zinc Coating: Durable hot dip galvanized finish resists corrosion.
  • ASTM F436 Certified: Required for many code-compliant applications.
  • 1-1/8" Compatibility: Pairs with galvanized structural bolts.
  • Flat Machined Surface: Delivers consistent torque transfer.

They had exactly what I needed

I ordered 100 F436 structural washers. They came within just a few days and were reasonably priced. I will definitely be ordering from Fasteners Plus again.
