Value Collection 31373 Sae Flat Washer No. 8 Screw Steel

Product Description

The VALUE COLLECTION 31373 is a No. 8 screw SAE flat washer manufactured from steel with a zinc-plated finish. SAE flat washers provide a bearing surface that distributes fastener load across a wider area, reducing the risk of surface damage and loosening under vibration. This washer measures 3/16 inches inner diameter, 7/16 inches outer diameter, and 3/64 inches thick. The zinc plating provides a basic level of corrosion resistance suitable for general indoor and light-duty applications. Electricians, HVAC technicians, plumbers, and general trade professionals use flat washers like this during equipment mounting, panel assembly, and fixture installation.

This SAE flat washer is suited for residential and light commercial applications wherever a No. 8 fastener is used. Common use cases include securing electrical enclosures, mounting HVAC components, assembling plumbing fixtures, and general panel or bracket work. The SAE washer standard specifies a larger outer diameter relative to the screw size compared to USS washers, making it a preferred choice when added load distribution is needed on softer or thinner substrate materials.

Key Features

• SAE flat washer standard for wider load distribution relative to screw size
• Steel construction provides reliable structural integrity for general fastening applications
• Zinc-plated finish offers basic corrosion resistance for indoor and light-duty use
• 3/16 inches inner diameter sized for No. 8 screws
• 7/16 inches outer diameter for adequate bearing surface coverage
• 3/64 inches thickness keeps profile low in tight assemblies

Compatibility

Designed for use with No. 8 screws and bolts in standard SAE inch-measurement fastening applications across HVAC, electrical, plumbing, and general mechanical assembly work.

Installation Notes

Place the washer on the fastener shank before driving into the substrate to ensure proper seating. Power down or de-energize any equipment before installing hardware near live electrical components, in accordance with NFPA 70 (NEC) lockout/tagout requirements. Verify that the washer inner diameter clears the screw shank without binding and that the outer diameter bears fully on the mating surface. Do not substitute this washer in applications requiring a USS washer specification or in environments with prolonged moisture or chemical exposure where a higher-grade corrosion-resistant finish is required.
