Value Collection FWSIS0500-1LBBX Sae Flat Washer 1/2 in

Product Description

The VALUE COLLECTION FWSIS0500-1LBBX is a 1/2 inch screw size SAE flat washer manufactured from steel with a zinc-plated finish. Flat washers distribute load across a fastened joint, reducing surface damage and preventing fastener pull-through. The zinc plating provides corrosion resistance suitable for general-purpose applications. This washer follows SAE dimensional standards, with a 17/32 inch inner diameter, a 1-1/16 inch outer diameter, and a 3/32 inch thickness. It is a single-piece unit appropriate for mechanical assembly, equipment maintenance, and trade installation work across multiple industries.

This SAE flat washer is suited for use wherever a 1/2 inch fastener requires load distribution or surface protection. Common applications include HVAC equipment assembly, electrical panel and conduit mounting, plumbing fixture installation, and general structural fastening in both residential and commercial settings. The inch-based dimensional system makes it compatible with standard SAE hardware commonly stocked in trade and maintenance environments.

Key Features

• SAE standard dimensions for consistent fit with 1/2 inch fasteners
• Steel construction for strength and durability under mechanical load
• Zinc-plated finish for corrosion resistance in general-purpose environments
• 17/32 inch inner diameter fits 1/2 inch screw shanks with proper clearance
• 1-1/16 inch outer diameter provides effective load distribution across the fastened surface
• 3/32 inch thickness meets SAE specification for this screw size class

Compatibility

Designed as a standard SAE flat washer for use with 1/2 inch screws and bolts in inch-measurement fastener assemblies across HVAC, plumbing, electrical, and general mechanical applications.

Installation Notes

Install with the washer seated flat against the mating surface before torquing the fastener. Ensure the inner diameter clears the fastener shank without excessive play. For corrosive or outdoor environments, evaluate whether additional corrosion protection is required beyond the zinc-plated finish. No special tools are required for installation; follow applicable code and equipment manufacturer guidelines for fastener torque requirements.
