Value Collection KP41013 Sae Flat Washer 1-1/2 in Steel

Product Description

The VALUE COLLECTION KP41013 is a steel SAE flat washer sized for 1-1/2 inch screws and fasteners. It features a zinc-plated finish that provides corrosion resistance in general-purpose applications. With a 1-9/16 inch inner diameter, a 3 inch outer diameter, and a thickness of 5/32 inch, this washer distributes load across a wide bearing surface. Electricians, plumbers, HVAC technicians, and mechanical contractors use SAE flat washers daily when assembling equipment mounts, pipe hangers, panel brackets, and structural connections. The zinc plating meets standard finishing requirements for indoor and light outdoor service environments.

This washer is suited for commercial and residential trade applications where a large-OD, load-spreading washer is required on 1-1/2 inch fasteners. Typical uses include equipment base mounting, duct support hardware, pipe hanger assemblies, and general mechanical assembly where SAE washer dimensions are specified. The inch-system dimensions conform to SAE flat washer standards, making this a direct fit wherever that specification is called out on drawings or in job specs.

Installation Notes

SAE flat washers are installed by any trade using bolted connections — HVAC, plumbing, electrical, and general mechanical. Place the washer on the fastener shank before threading the nut or driving into the substrate to distribute clamping load and prevent surface damage. Ensure the mating fastener and washer material are compatible to avoid galvanic corrosion in wet or outdoor environments. Follow applicable code requirements for the assembly type being performed.
