Value Collection 73019093-100 M4 Flat Washer 316 Ss Din 125A

Product Description

The VALUE COLLECTION 73019093-100 is a standard flat washer sized for M4 screws and fasteners, manufactured from Grade 316 stainless steel with a plain finish. It conforms to DIN 125A, the widely recognized metric standard for flat washers used across industrial, mechanical, and plumbing applications. The washer measures 4.3 millimeters inside diameter and 9 millimeters outside diameter. Grade 316 stainless steel provides enhanced corrosion resistance compared to Grade 304, making it well suited for wet, marine, and chemically exposed environments. This part ships in a minimum order quantity of 100 pieces per pack and is used by tradespeople, maintenance technicians, and mechanical contractors working with metric fastener assemblies.

This flat washer is appropriate for residential and commercial mechanical installations wherever M4 metric fasteners are used. Common applications include HVAC equipment mounting, plumbing fixture assembly, electrical panel and enclosure work, and general equipment fabrication. The DIN 125A standard ensures dimensional consistency, allowing reliable interchange with other compliant hardware in metric assemblies. Trades working in coastal, poolside, or high-humidity environments will find the Grade 316 alloy especially practical due to its resistance to chloride-induced corrosion.

Installation Notes

Installation is performed by any trade technician assembling or servicing metric-fastened equipment. Ensure mating surfaces are clean and free of debris before placing the washer. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Follow applicable mechanical and structural codes for fastener torque and assembly requirements.
