Value Collection 31378 Sae Flat Washer 3/8 in Steel Zinc

Product Description

The VALUE COLLECTION 31378 is a zinc-plated steel SAE flat washer designed for 3/8 inch screw applications. It features an inside diameter of 13/32 inches, an outside diameter of 13/16 inches, and a thickness of 1/16 inch. The zinc plating provides corrosion resistance for general-purpose fastening tasks. SAE flat washers distribute load across a wider bearing surface, reducing the risk of fastener pull-through or surface damage. This washer is used by electricians, plumbers, HVAC technicians, and general contractors wherever a standard inch-series flat washer is required to complete a bolted connection.

This SAE flat washer is suited for residential and light commercial construction, mechanical assemblies, equipment mounting, and service work across the trades. It conforms to SAE dimensional standards for 3/8 inch screw size, making it compatible with the wide range of standard hex bolts, machine screws, and carriage bolts used in everyday fastening applications. Sold individually per package with a minimum order quantity of 250 pieces.

Key Features

Compatibility

Designed for use with 3/8 inch screws, bolts, and fasteners conforming to SAE inch-series standards. Suitable for general mechanical, structural, and trade fastening applications where an SAE flat washer is specified.

Installation Notes

Place the washer over the fastener shank before threading the nut or driving the fastener into the workpiece. Ensure the inside diameter seats cleanly over the bolt without binding. No special tools are required for installation. Observe applicable mechanical and electrical codes when using fasteners in structural or panel-mounted applications.
