Value Collection FWSIS1250-025BX Sae Flat Washer 25 Pack

Product Description

The VALUE COLLECTION FWSIS1250-025BX is a zinc-plated steel SAE flat washer sized for 1-1/4 inch screws. It features a 1-3/8 inch inside diameter, a 2-1/2 inch outside diameter, and a 5/32 inch thickness. SAE flat washers distribute clamp load across a broader surface area than standard washers, reducing fastener pull-through and protecting mating surfaces. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and light-duty applications. This washer is supplied in minimum quantities of 25 and is used by plumbers, pipefitters, electricians, HVAC mechanics, and general maintenance technicians wherever a 1-1/4 inch fastener requires load distribution.

This washer is appropriate for residential and light commercial mechanical, plumbing, and electrical installations. Common use cases include equipment mounting, pipe hanger assemblies, panel and bracket fastening, and general structural bolting tasks where a 1-1/4 inch screw or bolt is specified. The SAE dimensional standard makes this washer a straightforward drop-in for any application calling out SAE flat washer sizing at the 1-1/4 inch screw size. Sold in a 25-piece box, this item suits job-site restocking or small project needs.

Installation Notes

Installation requires no special tools beyond standard wrenches or sockets sized for the mating fastener. Always de-energize electrical systems and shut off fluid supply before servicing any assembly that requires washer replacement or installation. Ensure the washer seats flat against the mating surface with no debris or burrs underneath, as an uneven seating surface can reduce clamp load uniformity. Verify that zinc-plated hardware is acceptable for the environment — substitute a stainless or hot-dip galvanized washer where elevated corrosion exposure is present.
