Value Collection FWSIS0370-10LBBX Sae Flat Washer

Product Description

The VALUE COLLECTION FWSIS0370-10LBBX is a 3/8 inch SAE flat washer made from steel with a zinc-plated finish. SAE flat washers distribute load across a fastener bearing surface, reducing stress on the mating material and helping prevent pull-through in bolted assemblies. This washer measures 13/32 inches inside diameter, 13/16 inches outside diameter, and 1/16 inch thick. The zinc plating provides a basic level of corrosion resistance suitable for general indoor and light-duty outdoor applications. Installers working in HVAC, plumbing, electrical, and general mechanical service will find this washer appropriate for standard 3/8 inch fastener assemblies across a wide range of field tasks.

This SAE flat washer is intended for use with 3/8 inch screws and bolts in residential and light commercial applications. Common install scenarios include equipment mounting, panel assembly, pipe bracket attachment, and general mechanical fastening where load distribution is needed. The SAE standard sizing provides a larger outer diameter relative to USS washers, making it a preferred choice where wider bearing surface coverage is required.

Key Features

• Steel construction for reliable strength in standard fastening applications
• Zinc-plated finish for basic corrosion resistance
• SAE standard dimensions: 13/32 inches ID, 13/16 inches OD, 1/16 inch thick
• Fits 3/8 inch screw and bolt sizes
• Wider bearing surface compared to USS washers of the same screw size

Compatibility

Designed as a standard SAE flat washer for use with 3/8 inch fasteners in general mechanical, HVAC, plumbing, electrical, and light industrial assembly applications.

Installation Notes

Install with hand tools appropriate to the fastener being used. Ensure the washer seats flush against the mating surface before final torque is applied to the fastener. In outdoor or high-moisture environments, consider whether zinc plating alone provides adequate corrosion protection for the application. No specialized trade license is required for general fastener installation, though work on code-governed systems should follow applicable NEC, IFGC, or IPC requirements.
