Bowmalloy 500014 Sae Flat Washer 5/16 Inch Carbon Steel

Product Description

The BOWMALLOY 500014 is an SAE flat washer designed for use with 5/16 inch fasteners in structural and mechanical assembly applications. Made from Grade 8 carbon steel with a yellow zinc chromate finish, it meets ASTM F436 specifications for load distribution and corrosion resistance. The washer measures 0.334 inches inside diameter, 0.687 inches outside diameter, and 0.078 inches thick. It is suitable for use in bolted connections where a wider bearing surface is needed to distribute clamping load or protect the mating surface. Installers in HVAC, plumbing, electrical, and general mechanical trades will find this a standard fit for everyday fastener assemblies.

This washer is used in residential and commercial construction and equipment installation where SAE-standard flat washers are specified. It is well suited for use with 5/16 inch bolts and screws in steel-to-steel and steel-to-substrate connections. The yellow zinc chromate finish provides a moderate level of corrosion resistance, making it appropriate for indoor and moderately protected outdoor environments. Sold individually with a minimum order quantity of 100 pieces.
