Value Collection USFW1130025OZ Uss Flat Washer 1-1/8 in

Product Description

The VALUE COLLECTION USFW1130025OZ is a USS flat washer designed for use with 1-1/8 inch screws and bolts. Manufactured from steel with a zinc-plated finish, this washer provides a broad bearing surface that distributes load and reduces fastener pull-through in structural and mechanical assemblies. The USS series specifies a wider outer diameter than SAE washers of the same screw size, making it the correct choice when bearing surface area is a priority. This package contains 25 washers, suitable for job-site stocking or production-line use. Installation requires no special tooling beyond standard hand or impact wrenches.

This washer is used in general construction, mechanical maintenance, plumbing rough-in, HVAC equipment mounting, and electrical panel framing wherever a 1-1/8 inch fastener is specified. The wider USS outer diameter is commonly selected for wood framing, strut channel connections, and equipment base mounting where softer substrate materials require load spreading. The zinc-plated finish offers moderate corrosion resistance for interior and protected exterior applications. Tradespeople in plumbing, HVAC, and electrical work routinely stock USS flat washers across multiple screw sizes for bracket and equipment anchoring tasks.

Key Features

• USS flat washer profile provides a wider outer diameter than SAE equivalents for increased load distribution
• Steel construction with zinc-plated finish for durability and moderate corrosion resistance
• 1-1/8 inch nominal screw size with 1-1/4 inch inside diameter for proper fastener fit
• 2-3/4 inch outside diameter spreads clamping load over a broad bearing surface
• 0.136 inch thickness meets USS dimensional standards
• Sold in a minimum order quantity of 25 pieces for efficient job-site and shop stocking

Compatibility

Designed for use with 1-1/8 inch USS-standard screws and bolts in inch-measurement fastener assemblies across general construction, mechanical, and trade applications.

Installation Notes

Install using standard hand tools or impact wrenches appropriate to the fastener size. Ensure the washer seats flat against the substrate before final torque is applied to the fastener. For exterior or wet environments, evaluate whether a higher-grade corrosion-resistant finish is required beyond what zinc plating provides. No special trade license is required to install flat washers, but fastener assembly should follow applicable structural or mechanical codes for the application.
