Value Collection MSC-09181975 Fender Flat Washer 316 Ss

Product Description

The VALUE COLLECTION MSC-09181975 is a fender flat washer designed for size 10 screws, manufactured from Grade 316 stainless steel with a plain finish. Fender washers feature a larger-than-standard outside diameter relative to the inside diameter, distributing load over a wider surface area to reduce pull-through on thin or soft materials. With a 0.223 inch inside diameter and a 1 inch outside diameter, this washer seats flush against fastener heads and mating surfaces without added coatings or plating. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making this washer suitable for wet, coastal, and chemical-exposure environments.

This washer is used in plumbing, HVAC, electrical, and general mechanical applications where a size 10 screw or bolt requires a broad bearing surface. It is well suited for installations involving sheet metal, fiberglass, plastic panels, or other materials prone to pull-through. The plain finish keeps the washer ready for use as supplied with no additional prep required. Typical installers include plumbers, HVAC technicians, electricians, and maintenance professionals working on equipment panels, pipe supports, duct hangers, and similar assemblies.

Installation Notes

Installation requires no special tools beyond standard hand or power drivers appropriate for the mating fastener. Shut down and de-energize any equipment before servicing panels or assemblies where washers are being replaced or added. Ensure the washer seats flat against the mating surface with no debris or burrs that could cause uneven clamping. Follow applicable codes including NEC, IPC, or IFGC as relevant to the assembly being serviced.
