Value Collection FWSIS0-30-100BX Sae Flat Washer 100 Pack

Product Description

The VALUE COLLECTION FWSIS0-30-100BX is a No. 3 screw-size SAE flat washer manufactured from steel with a zinc-plated finish. Flat washers distribute clamp load across a fastened joint, protecting the mating surface and reducing loosening under vibration. The SAE specification means this washer follows standard dimensions for general mechanical and structural fastening applications. The zinc plating provides basic corrosion resistance suitable for indoor and light-duty environments. Each package contains 100 washers, making this box quantity practical for production assembly, maintenance kits, and service truck stock.

This washer fits No. 3 screw fasteners and is used in light mechanical assemblies, HVAC equipment panels, electrical enclosures, and plumbing fixture mounting where a thin, small-diameter load-spreading washer is required. The SAE flat washer profile is appropriate for applications where a tighter outside diameter is preferred over the broader coverage of an USS-spec washer. Suitable for residential and light commercial service work where zinc-coated steel hardware meets the corrosion and load requirements.

Key Features

• SAE flat washer profile for No. 3 screw fasteners
• Steel construction with zinc-plated finish for basic corrosion resistance
• Inside diameter of 7/64 inches fits snugly around No. 3 screw shank
• Outside diameter of 1/4 inch and thickness of 1/64 inch for low-profile load distribution
• Box quantity of 100 washers for production use or service stock

Compatibility

Designed as a standard SAE flat washer for No. 3 screw fasteners in general mechanical, HVAC, electrical, and plumbing assembly applications requiring inch-measurement hardware.

Installation Notes

Install using standard hand tools appropriate for the fastener type. Ensure the washer seats flat against the mating surface before torquing the fastener. Power down or de-energize any electrical equipment before performing fastener service on enclosures or panels. Zinc-plated steel is not recommended for direct outdoor exposure or high-moisture environments where stainless or hot-dip galvanized hardware would be more appropriate.
