DIN 125 flat round washer — galvanised
Flat washer for bolted joints | Galvanised steel | Sizes M3–M56
Product description
The flat round washer to DIN 125 is a basic component used in bolted joints. It is fitted between the head of a bolt or nut and the surface of the fastened component to distribute the load evenly and minimise the risk of material damage during tightening.
The product is made of steel and coated with a layer of zinc. The zinc coating provides basic protection against corrosion under typical conditions of use. The washer is designed for use with bolts, nuts and threaded rods of the appropriate size.
DIN 125 washers are a versatile choice for construction, installation, workshop, machinery and industrial applications. The available sizes, ranging from M3 to M56, allow the washer to be adapted to common metric fastenings.
