Value Collection 81923922 Sae Flat Washer 1/2 in Steel Zinc

Product Description

The VALUE COLLECTION 81923922 is a zinc-plated steel SAE flat washer sized for 1/2 inch screws. SAE flat washers distribute load across a fastened joint, reducing surface damage and preventing pull-through on bolted connections. This washer carries a 0.521 inch inside diameter, a 1.092 inch outside diameter, and a 0.121 inch thickness, conforming to SAE dimensional standards. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and light-duty outdoor applications. Sold in a pack of 25, these washers are a standard consumable for mechanical assembly, structural fastening, and equipment maintenance across plumbing, HVAC, electrical, and general trade work.

SAE flat washers in this size class are used wherever a 1/2 inch fastener requires a wider bearing surface. Common install scenarios include equipment mounting, pipe hanger assemblies, electrical panel brackets, and structural steel connections. The SAE series uses a larger OD-to-screw-size ratio compared to USS washers, making them preferred when load spread across softer materials or painted surfaces is a priority. These are appropriate for use by plumbers, HVAC technicians, electricians, and general contractors handling day-to-day fastener needs on the job site or in the shop.

Key Features

• 0.521 inch ID fits 1/2 inch screw diameter with standard clearance
• 0.121 inch thickness meets SAE dimensional requirements
• Steel construction with Grade 2 material rating for general-purpose strength
• Zinc-plated finish for corrosion resistance in typical indoor environments
• Pack of 25 for stocking and repetitive-task efficiency

Compatibility

Designed as an OEM-style replacement and general-use SAE flat washer for 1/2 inch fastener applications across trade and industrial assemblies.

Installation Notes

Install using standard hand tools; seat the washer flat against the bearing surface before tightening the fastener. Inspect the washer for burrs or deformation before use to ensure proper load distribution. For corrosive or outdoor wet environments, consider stainless or hot-dip galvanized alternatives, as zinc plating offers limited protection under prolonged moisture exposure. No special certifications or licensed trade classifications are required for washer installation.
