1" Conquest F436 Flat Washer – Plain Finish

This 1" F436 washer is purpose-built for structural fastening systems that demand precision and strength. Its plain finish is ideal for use in non-corrosive indoor environments. Precision machining ensures consistent performance when used with high-strength bolts. Perfect for use with 1" coarse or fine-thread A325/A490 bolts.

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

1" Structural Washer for Framing and Infrastructure Installs

This washer is trusted in structural framing, bridge supports, and equipment base plates. The thick, hardened design ensures even load transfer and helps prevent bolt embedment. Built to ASTM F436 standards, it holds steady under torque and stress. Best for critical bolted connections in dry indoor spaces.

Key Features

  • Tempered Carbon Steel: Holds up to structural torque demands.
  • Plain Finish: Suitable for protected environments.
  • 1" Fastener Fit: Matches both fine and coarse threads.
  • ASTM Certified: Built for A325 and A490 bolt compatibility.
  • Flat Seating: Prevents fastener head distortion and slippage.

Common Applications

  • Bridge girder bolting
  • Steel structure tie-ins
  • Column foot anchoring
  • Heavy equipment installation
  • Critical fastening infrastructure

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.

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.
