Value Collection BDNA-MP43983 M8 Standard Flat Washer

Product Description

The VALUE COLLECTION BDNA-MP43983 is a standard flat washer sized for M8 fasteners and manufactured from steel with a zinc-plated finish. Flat washers distribute the load of a threaded fastener across a broader surface area, reducing the risk of surface damage and fastener pull-through in structural and mechanical assemblies. This washer conforms to DIN 125, the metric standard governing flat washer geometry, and carries a material grade of 12.9. The zinc plating provides a basic layer of corrosion resistance suited for general indoor and light-duty outdoor applications. With a 9mm inside diameter and an 18.5mm outside diameter, the washer fits M8 screws, bolts, and threaded rod without modification.

This washer is used across a wide range of trade and industrial applications including HVAC equipment mounting, electrical panel and conduit support, plumbing fixture installation, and general mechanical assembly. It is appropriate for both residential and light commercial work wherever M8 fasteners require load distribution against a mating surface. Technicians in HVAC, electrical, and plumbing trades routinely stock metric flat washers of this type as a general-purpose hardware component. The minimum order quantity is 100 pieces.

Installation Notes

Install with the washer seated flush against the mating surface before tightening the fastener to ensure proper load distribution. Inspect the seating surface for burrs or debris that could compromise the washer's contact area. Zinc-plated steel washers are not recommended for submerged or highly corrosive environments without additional protective measures. No special tools are required for installation.
