Description

1-1/2" Conquest F436 Flat Washer – Plain Finish

This 1-1/2" F436 washer offers critical support in the most demanding structural bolting applications. Designed for compatibility with both coarse and fine threads, it ensures stability in large-diameter bolt assemblies. Its plain finish suits interior or controlled installs where corrosion resistance isn’t required. Manufactured from hardened carbon steel for maximum load-bearing reliability.

Ensure washer, bolt, and nut sizes match and meet structural specifications for safety and compliance.

1-1/2" F436 Washer for Infrastructure and Industrial Fastening

Use this washer where fastener strength and surface integrity are non-negotiable—bridges, high-rise framing, and critical mechanical foundations. It delivers even pressure distribution and resists compression under heavy torque. Built to meet ASTM F436 for structural bolts. A top choice for serious steelwork and equipment anchoring.

Key Features

  • 1-1/2" Inner Diameter: Built to fit structural bolts securely.
  • ASTM F436 Compliant: Required for certified fastening systems.
  • Plain Carbon Steel: Best for non-corrosive environments.
  • Dual Thread Compatible: Works with fine or coarse bolt threads.
  • Flat, Rigid Design: Protects joint integrity under load.

Common Applications

  • Bridge and overpass assemblies
  • Structural steel beams and columns
  • Heavy base plate mounting
  • Commercial equipment frameworks
  • Industrial retrofit and repair

Installation Tips

  • Install between bolt head or nut and the base material.
  • Use only with matching structural bolts and nuts.
  • Torque to specification to prevent movement or loosening.

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.
