Value Collection 37WUSSGPK Uss Flat Washer 3/8 in Steel

Product Description

The VALUE COLLECTION 37WUSSGPK is a USS flat washer designed for use with 3/8-inch screws and bolts. Manufactured from steel with a galvanized finish, it meets the ASME B18.22.1 standard for inch-series flat washers. The USS pattern provides a larger outer diameter than SAE-series washers, spreading clamp load over a wider bearing surface. This makes it well suited for general construction, mechanical assembly, and trade installations where load distribution and corrosion resistance are both required. Installation is straightforward and does not require specialized tools.

This washer is used in a wide range of residential and commercial applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and junction box assembly, and structural fastening. The galvanized coating provides corrosion resistance suitable for indoor and outdoor use in non-submerged environments. It is sold in a minimum order quantity of 100 pieces per order, making it appropriate for job-site stock or service vehicle inventory.

Key Features

• USS flat washer pattern with larger OD for increased load distribution compared to SAE series
• Steel construction with galvanized finish for corrosion resistance
• Meets ASME B18.22.1 inch-series flat washer standard
• 7/16 inch inside diameter fits 3/8 inch fastener shank with standard clearance
• 1 inch outside diameter and 5/64 inch thickness for consistent bearing surface

Compatibility

Designed for use with 3/8-inch screws and bolts in standard inch-series fastener applications across HVAC, plumbing, electrical, and general mechanical assembly.

Installation Notes

Install between the fastener head or nut and the mating surface to distribute clamping load. Ensure the washer seats flat against the bearing surface before torquing the fastener. Galvanized washers are suitable for general outdoor use but should not be used in direct contact with pressure-treated lumber containing copper-based preservatives without specifying compatible hardware. No special tools are required for installation.
