Bowmalloy KP80415 Sae Uss Flat Washer 7/16 Inch

Product Description

The BOWMALLOY KP80415 is a 7/16 inch SAE and USS flat washer manufactured from Grade 9 carbon steel with a clear zinc chromate finish. It is designed to distribute fastener load across a bearing surface, reducing the risk of surface damage and fastener pull-through in bolted assemblies. The inside diameter measures 0.459 inches, the outside diameter measures 0.921 inches, and the thickness is 0.093 inches. This washer meets ASTM F436 fastener standards and is appropriate for structural and general mechanical applications where corrosion resistance and dimensional accuracy are required. Plumbers, electricians, HVAC technicians, and general contractors use flat washers of this type during equipment mounting, pipe support installation, and structural assembly work.

This washer is suited for residential and light commercial construction and mechanical service applications. The dual SAE and USS rating means it meets both the Society of Automotive Engineers and United States Standard dimensional specifications, making it a versatile fit for a wide range of fastener assemblies. It is commonly used when installing equipment frames, mounting brackets, pipe hangers, and electrical panels where a standard 7/16 inch fastener is specified.

Key Features

• Dual SAE and USS rating for broad dimensional compatibility
• Grade 9 carbon steel construction for strength in bolted assemblies
• Clear zinc chromate finish provides corrosion resistance in moderate environments
• Meets ASTM F436 fastener standard
• Inside diameter of 0.459 inches fits standard 7/16 inch fasteners
• Thin 0.093 inch profile minimizes stack height in tight assemblies

Compatibility

Designed for use with 7/16 inch screws and bolts in standard SAE and USS fastener applications meeting ASTM F436 dimensional requirements.

Installation Notes

Flat washers of this type are installed by any trade requiring load distribution under a bolt head or nut. Always power down or de-energize equipment before fastening near electrical components. Use appropriate torque specifications as defined by the fastener manufacturer or relevant code, such as the NEC for electrical installations or the IFGC for gas equipment mounting. Do not substitute washer grades in structural applications without verifying load requirements.
