High Tensile SS 304 SS 316 A2 A4 Bright Screw Nut And Washer , Plain Flat Washer
1. Descriptions:
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. Crever Fastener Factory offers over 500,000 unique fastener products from stock in inch and metric standard in a variety of materials and finishes.
