Value Collection 39752 Uss Flat Washer 3/8 in Steel

Product Description

The VALUE COLLECTION 39752 is a USS flat washer sized for 3/8-inch screws, manufactured from steel with a zinc yellow dichromate finish. It carries a Material Grade 8 rating and is produced to USS (United States Standard) dimensional specifications, which call for a wider outer diameter than SAE equivalents for greater load distribution. The zinc yellow dichromate coating provides corrosion resistance in moderate-exposure environments. This washer is a standard fastener component installed by electricians, plumbers, HVAC technicians, pipefitters, and general contractors wherever a bearing surface is needed under a bolt head or nut.

This washer is suited for a broad range of mechanical assemblies, structural connections, and equipment mounting applications in residential and light commercial construction and service work. The wider OD relative to screw size makes it a good fit for soft or oversized substrate materials where point loading must be spread. It is sold in individual units with a minimum order quantity of 200 pieces, making it appropriate for stocking in shop or service vehicle inventory.

Key Features

• USS series profile provides wider outer diameter for increased load-bearing surface compared to SAE washers of the same screw size
• Material Grade 8 steel construction for high tensile strength in demanding fastener assemblies
• Zinc yellow dichromate finish delivers corrosion resistance in moderate-moisture environments
• 7/16-inch ID provides correct clearance fit over a 3/8-inch fastener shank
• Consistent 5/64-inch thickness meets USS dimensional standards for reliable stack-up in multi-fastener assemblies

Compatibility

Designed as a standard USS flat washer for use with 3/8-inch screws and bolts in general mechanical, construction, and trade-service applications.

Installation Notes

Installation requires no special tooling beyond the wrench or driver used to drive the fastener. Place the washer between the fastener head or nut and the substrate surface before tightening. Do not substitute this washer in applications that specify SAE dimensional tolerances without confirming OD clearance requirements. Ensure fastener grade and finish are compatible with the washer material to avoid galvanic incompatibility in corrosion-sensitive installations.
