Value Collection BDNA-MP43985 M12 Flat Washer Steel

Product Description

The VALUE COLLECTION BDNA-MP43985 is a standard flat washer designed for M12 screw fastener applications. Manufactured from steel with a zinc-plated finish, this washer distributes load across a fastened joint and helps protect mating surfaces from damage during assembly. It meets the DIN 125 fastener standard and is sized at 13.5 mm inside diameter by 25 mm outside diameter with a 2.5 mm thickness. The zinc plating provides a baseline level of corrosion resistance suited for general mechanical assembly. Plumbers, electricians, HVAC technicians, and general maintenance trades routinely use flat washers like this one in equipment mounting, panel installation, and pipe support applications.

This washer is appropriate for use in both residential and commercial settings wherever M12 fasteners are used to secure components. Typical applications include equipment bases, structural brackets, pipe hangers, and junction box mounting in trade and light industrial environments. The metric sizing and DIN 125 compliance make it a straightforward fit for metric-standard fastener assemblies. Sold individually per package with a minimum order quantity of 50 pieces.

Compatibility

Designed as a DIN 125 standard metric flat washer for use with M12 fasteners in general mechanical, plumbing, HVAC, and electrical trade assembly applications.

Installation Notes

Flat washers are installed by trades such as HVAC technicians, plumbers, and electricians during equipment mounting and structural fastening work. Always de-energize electrical systems and shut off relevant services before performing fastener work near live components or pressurized lines. Use appropriate hand tools and torque equipment suited to M12 hardware and follow applicable codes such as the NEC or IPC where fastener assemblies intersect with regulated installations. Do not reuse washers that show signs of deformation or corrosion.
