Value Collection A410353 M5 Flat Washer 316 Ss 50-pack

Product Description

The VALUE COLLECTION A410353 is an M5 standard flat washer manufactured from Grade 316 stainless steel with a plain finish. Conforming to DIN 125A, this metric washer measures 5.3mm inner diameter and 10mm outer diameter. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making it a reliable choice for demanding environments where exposure to moisture, chemicals, or salt air is a factor. Each package contains 50 washers. Plumbers, electricians, HVAC technicians, and general trade professionals use these washers daily to distribute fastener load and protect mating surfaces during assembly.

These M5 flat washers are suited for use across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and enclosure assembly, and general mechanical fastening tasks. The metric M5 sizing and DIN 125A standard make them appropriate for use with M5 screws and bolts in both new construction and repair or retrofit work. The 50-piece package quantity supports small-to-medium jobs without requiring bulk procurement.

Installation Notes

Installation requires no special tooling beyond standard hand or power fastening equipment. Ensure mating surfaces are clean and free of debris before assembly to maintain proper clamp load. When working on electrical enclosures or panels, de-energize the circuit and follow applicable NEC guidelines before beginning fastener work. For plumbing or HVAC applications, shut off relevant supply lines or system power prior to disassembly and reassembly.
