Description

1-1/8" Conquest F436 Flat Washer – Plain Finish

Engineered for structural bolt systems, this 1-1/8" F436 washer offers dependable performance in high-load, indoor installations. Its plain finish helps control costs in environments where corrosion isn’t a concern. Precision-machined and hardened, it resists crushing and deformation under torque. Suitable for use with both fine and coarse thread bolts.

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

1-1/8" F436 Washer for Heavy Fastening Jobs

This washer provides critical stability for bridges, industrial framing, and steel-to-steel connections. It distributes pressure evenly to reduce material damage and maintain long-term joint integrity. Use it where large-diameter bolts are required and failure is not an option. Designed to meet ASTM F436 standards for strength and reliability.

Key Features

  • Hardened Steel Construction: Built for torque and tensile load handling.
  • Plain Finish: Best for dry, non-corrosive environments.
  • 1-1/8" ID: Matches industry-standard structural bolts.
  • Supports Fine and Coarse Threads: Versatile field compatibility.
  • Uniform Machining: Ensures smooth, flat fit under pressure.

Common Applications

  • Structural joints and plates
  • Bridge and truss hardware
  • Heavy machine installs
  • Utility framework support
  • Indoor infrastructure systems

Installation Tips

  • Install between bolt head or nut and the base material.
  • Use only with matching structural bolts and nuts.

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.
