1020 Steel Commercial Flat Washers - Request for Information


1020 Steel: is a plain carbon steel grade providing increased strength and ductility.  1020 steel retains integrity in basic structural applications while still being a low cost material.


Commercial:  refers to those industries developing and manufacturing products for consumer use.  While the industrial term is broad, commercial components must comply with all product and application criteria to provide functionality, and in many cases, a cosmetically and commercially appealing quality.


Flat Washers:  primarily used with other hardware, such as nuts and bolts to distribute forces in the process of tightening.  Tightness is determined by pattern features such as nominal screw sizes, screw pitch thread, interior and exterior diameter ratios and height. 


Washers: circular hardware used for spacing, load distribution, sealing and vibration reduction.  Washers are produced through stamping and shaping a variety of materials including various metal, plastic, rubber and fiber.
