Plain Washer (DIN 125)
Equivalent Standard: ISO 7089 | UNI 6592
High hardness and low deformation plain washers, punched washers, and flat washers from BRK Industries can be used as a spacer or a load distributor. The washers are designed for environmental protection. Washers from BRK Industries also provide abrasion resistance and corrosion prevention. With good electrical and thermal conductivity, our washers can be used in sheet metal work, plumbing, auto body construction and repair, and other electrical applications.
For long-lasting durability, the washers are made with high-quality steel, brass, and other materials. The washers come in large diameters for specific applications requiring a good amount of surface load reduction. Plain washers also provide insulation against heat and electricity and prevent the threaded material from taking the heat. Our flat and punched washers are mostly used to spread the load over a wide surface and act as a barrier between the fastener and surface when the hole is larger than the nut.

DIN 125
Metric DIN 125 Flat Washers are standard metric flat washers – a circular metal disc with a central hole. Typically used to distribute the load over a larger bearing surface either positioned below the head of a bolt or below the nut. This even distribution over a larger area reduces the chance of damaging the bearing surface. A washer could also be used if the outer diameter of a mating nut is smaller than the hole through which the screw is placed. BRK Industries offers over 500,000 unique fastener products from stock in inch and metric standard in a variety of materials and finishes. The following sizes of DIN 125 Flat Washers are available for immediate shipping from stock: Diameters ranging from M3 to M72 in aluminum, brass, nylon, steel as well as stainless steel A2 and A4.
