Description

Conquest USS Flat Washers with a hot dip galvanized finish are built for strength, durability, and lasting performance. Designed for use in high-load environments, these washers distribute the load of a threaded fastener, reduce surface wear, and help prevent fastener pull-through. Whether you're working on structural steel, outdoor construction, or heavy-duty framing, these washers provide the performance and protection your job demands.

Each washer is hot dip galvanized to deliver a thick, corrosion-resistant coating, ideal for outdoor and marine environments where moisture and exposure are a constant concern. The oversized outer diameter of USS washers makes them perfect for applications requiring more surface coverage around the bolt head or nut.

Compatible with a wide variety of fasteners, these flat washers come in multiple diameters to match your exact hardware specs. That means fewer complications on-site and a more secure, lasting hold.

Key Features:

  • Heavy-Duty Construction: Manufactured to USS standards for larger outside diameter and reliable load distribution.
  • Hot Dip Galvanized Finish: Provides robust corrosion resistance, ideal for exterior, marine, or treated lumber applications.
  • Versatile Use: Commonly used with bolts and nuts in construction, steel assembly, and infrastructure jobs.
  • Easy Installation: Slide over bolts or threaded rods to reinforce joints and prevent embedment into softer materials.
  • Available Options: Offered in multiple inside diameters and thicknesses to pair with a wide range of bolts and threaded hardware.

Common Applications:

  • Structural framing and post-installation
  • Outdoor decking and treated lumber projects
  • Marine and coastal construction
  • Steel-to-wood and steel-to-steel joints
  • Pole barn and utility building assemblies
