Description

1-1/4" Conquest USS Flat Washer – Plain Finish

This 1-1/4" USS washer is engineered for maximum support in structural and mechanical fastening applications. Its broad outer diameter spreads clamping force, preventing surface damage and material compression. The plain finish is best for interior use where corrosion isn’t a concern. Works with 1-1/4" coarse-thread bolts and nuts for heavy-duty connections.

For best results, always match your washer, bolt, and nut material and finish to ensure proper fit and performance.

1-1/4" USS Washer for Industrial and Utility Anchoring

Ideal for utility structure builds, flange joints, and anchor point reinforcement. This washer holds up under vibration and stress without distortion. The plain steel finish is smooth and reliable in controlled environments. Perfect for retrofits, custom builds, and utility hardware installations.

Key Features

  • Large Format: Designed to support big bolt heads or nuts.
  • USS Profile: Thick and wide for optimal load spreading.
  • Plain Finish: Use in indoor applications where rust isn’t a concern.
  • 1-1/4" ID: Fits standard coarse-thread hardware.
  • Dependable Under Load: Won’t distort under pressure.

Common Applications

GREAT SERVICE

Great service

The exact size washer I needed in a quantity I needed that no other business seemed to have. Very good price, even with delivery charges, that big box stores by almost 75%. That and the quick delivery means I can go to fasteners+ for future needs and not have to shop around for the best deal.
