Value Collection A997394 Standard Flat Washer 18-8 Ss 5 Pack

Product Description

The VALUE COLLECTION A997394 is a standard flat washer sized for 1-1/4 inch screws, manufactured from grade 18-8 stainless steel. It measures 1.312 inches inside diameter, 2.75 inches outside diameter, and 0.125 inches thick. Grade 18-8 stainless steel provides solid corrosion resistance in wet, outdoor, and marine-adjacent environments. This washer distributes fastener load across a wider surface area, reducing pull-through and protecting the mating material. Plumbers, pipefitters, electricians, and HVAC technicians reach for this style of washer when assembling equipment panels, pipe supports, and mechanical connections where standard hardware is specified. Sold in a package of 5.

This washer fits standard 1-1/4 inch fastener assemblies across a wide range of trade applications. It is appropriate for structural and non-structural connections in plumbing rough-in, HVAC equipment mounting, electrical enclosure assembly, and general mechanical installation. The inch-system sizing makes it compatible with standard SAE and inch-series bolt and nut combinations. Its stainless steel construction makes it suitable for applications where carbon steel hardware would corrode over time, including damp mechanical rooms, rooftop installations, and outdoor equipment pads.

Installation Notes

Installation requires no special tools beyond standard hand or power wrenches appropriate to the fastener being used. Place the washer against the mating surface before seating the nut or bolt head to ensure proper load distribution. Confirm the fastener grade and torque requirements match the assembly specification before final tightening. Stainless steel fastener components can be prone to galling under high torque — apply an appropriate anti-seize compound when assembling stainless-to-stainless connections.
