Value Collection 91769 1/2 in Brass Flat Washer

Product Description

The VALUE COLLECTION 91769 is a standard flat washer designed for use with 1/2 inch screws and fasteners. Manufactured from brass with a plain finish, this washer distributes load across the fastener head or nut to protect mating surfaces and reduce the risk of loosening under vibration. With an inside diameter of 0.562 inches, an outside diameter of 1.125 inches, and a thickness of 0.091 inches, it meets standard dimensional tolerances for inch-series flat washers. Plumbers, electricians, HVAC technicians, and general maintenance trades use brass washers where corrosion resistance and electrical conductivity are priorities.

This washer is suited for residential and light commercial fastening applications where a 1/2 inch screw or bolt is used. Brass construction makes it a practical choice in wet or humid environments, including plumbing rough-in work, electrical panel assemblies, and HVAC equipment mounting where ferrous hardware would be prone to corrosion. The plain finish requires no additional preparation prior to installation.

Key Features

• Brass construction provides natural corrosion resistance in wet and humid environments
• Plain finish — no coating or treatment required before use
• 0.562 inch inside diameter fits standard 1/2 inch screws and bolts
• 1.125 inch outside diameter provides effective load distribution across the bearing surface
• 0.091 inch thickness meets standard flat washer dimensional requirements
• Inch-series dimensioning for compatibility with standard SAE and ANSI fastener systems

Compatibility

Designed as a standard flat washer for use with 1/2 inch inch-series screws and bolts in general fastening applications across plumbing, HVAC, electrical, and mechanical assembly work.

Installation Notes

Install this washer between the fastener head or nut and the mating surface before torquing down the fastener. Brass is a softer material than steel — avoid over-torquing, which can deform the washer and reduce its load-distributing effectiveness. No special tools are required for installation beyond those used for the associated fastener. Follow applicable codes such as NEC or IPC when using hardware in electrical or plumbing assemblies.
