Technical Features
- USS Standard body geometry: Features a large, wider outside diameter compared to SAE flat washers, providing a broader load-bearing surface to better distribute clamping force across the fastened material.
- Thin flat plate profile with center hole: Designed to seat flush between the fastener head or nut and the mating surface, preventing pull-through and reducing surface damage under load.
- 3/8" nominal sizing: Matches standard 3/8" threaded fasteners for consistent fit without modification.
- Box quantity of 100 pieces: Supplied in bulk packaging suited for high-volume or ongoing assembly work, reducing per-unit cost and the need for frequent reordering.
Applications
- General construction and structural fastening where wide load distribution is required
- Mechanical assemblies using 3/8" bolts, screws, or threaded rods
- Wood and soft-material fastening where a larger bearing surface prevents pull-through
- Maintenance, repair, and operations (MRO) tasks requiring USS-specification hardware
