Washers are useful industrial parts that are often used with bolts and nuts and are manufactured in different shapes and with different purposes. Washers are usually manufactured with flat shape and spring shape also known as split lock washer. Just like the bolts and nuts, Washers follow international manufacturing standards that determine the inner diameter, outer diameter and thickness. The Metric washers that are assembled along with metric bolts and cap head screws and nuts follow DIN125 standard.

Split washers are usually used along with flat washers and are meant to increase the connecting tension and preload. they also help lock the connection and avoid loosening while dynamic loads are applied.
Standard Split washers are manufactured based on DIN127 Standard.
Metric flat washers are manufactured based on DIN125 and used often with hex bolts, stud bolts and Allen bolts in connection with nuts to properly propagate the load on the connecting surface and protecting them from abrasion while fastening.
Flat washers follow the material of the bolts and nuts and are delivered as plain or with Zinc plating.
