Value Collection 39702 Sae Flat Washer 5/16 in Steel

Product Description

The VALUE COLLECTION 39702 is an SAE flat washer designed for use with 5/16 inch screws and fasteners. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this washer provides corrosion resistance in general mechanical and structural assemblies. It measures 11/32 inches inner diameter, 11/16 inches outer diameter, and 1/16 inch thick, conforming to SAE standards for load distribution across a broad bearing surface. Electricians, plumbers, HVAC technicians, and general mechanical contractors use SAE flat washers to protect mating surfaces, distribute clamp load, and prevent fastener pull-through in both metal and wood substrates.

This washer fits standard 5/16 inch screw and bolt assemblies in light to medium-duty mechanical, plumbing, HVAC, and electrical enclosure applications. The SAE outside diameter is sized for use where a wider bearing surface is needed compared to USS or narrow-series washers. The zinc yellow dichromate coating makes it suitable for indoor and mildly corrosive environments. It is sold individually but must be ordered in multiples of 200 units.

Key Features

• Grade 8 steel construction for reliable tensile strength in fastener assemblies
• Zinc yellow dichromate finish resists corrosion in general indoor and light-duty environments
• SAE series sizing provides a wider bearing surface than narrow-series washers
• 11/32 inch ID fits standard 5/16 inch screws and bolts with minimal play
• 1/16 inch thickness keeps stack height low in tight clearance applications
• Inch measurement system; conforms to SAE flat washer dimensional standards

Compatibility

Designed as an SAE-standard flat washer for use with 5/16 inch screw and bolt fasteners in mechanical, HVAC, plumbing, and electrical assembly applications.

Installation Notes

Install with standard hand tools; ensure the washer is seated flat against the mating surface before tightening the fastener. Power down electrical panels or HVAC equipment before accessing internal fastener points. Do not substitute SAE washers for applications requiring USS or metric dimensional specifications without confirming clearance and bearing surface requirements. Verify finish compatibility with the surrounding environment, as zinc dichromate coatings are not rated for prolonged outdoor or high-humidity exposure.
