Value Collection FW5XX01200-100BX M12 Flat Washer 316 Ss

Product Description

The VALUE COLLECTION FW5XX01200-100BX is an M12 standard flat washer manufactured from Grade 316 stainless steel with a plain finish. Conforming to DIN 125A, this washer features a 13 mm inside diameter and a 24 mm outside diameter, making it a metric-dimensioned fastener component suited for distributing load and protecting mating surfaces under bolt or screw heads and nuts. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, particularly in chloride-rich and marine environments. Plumbers, pipefitters, electricians, and mechanical contractors reach for this washer on installations where long-term corrosion resistance is a priority.

This washer is used in residential and commercial applications where M12 fasteners are specified. Typical installation scenarios include pipe flange connections, equipment mounting, and structural assembly in wet, coastal, or chemically aggressive environments. The DIN 125A standard ensures dimensional consistency across metric fastener assemblies, allowing this washer to seat correctly against standard M12 bolt heads and nuts without shimming or modification.

Key Features

• Grade 316 stainless steel construction for excellent corrosion and chloride resistance
• Conforms to DIN 125A fastener standard for consistent metric dimensioning
• 13 mm inside diameter fits M12 fastener shafts with proper clearance
• 24 mm outside diameter distributes clamping load across mating surfaces
• Plain finish with no coating that could interfere with galvanic compatibility assessments
• Metric system of measurement for direct use in DIN and ISO fastener assemblies

Compatibility

Designed for use with M12 metric fasteners in assemblies requiring DIN 125A standard flat washers. Suitable wherever a standard M12 washer is specified in metric fastener assemblies.

Installation Notes

Installation is performed by the applicable trade mechanic, pipefitter, or electrician responsible for the bolted assembly. Ensure mating surfaces are clean and free of debris before seating the washer. Torque fasteners to the specification called out in the engineering drawing or applicable code for the joint being assembled. Do not mix stainless steel fastener hardware with dissimilar metals without reviewing galvanic compatibility for the service environment.
