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.

Milspec: Military standards are most often defined by an efficient operation and substantial longevity in inhospitable or rugged conditions and environments.

Belleville Washers: are non-flat, cupped washes that provide load-bearing and deflection properties due to a subtitle conical shape. In addition to introducing spring and flexibility characteristics to the seal, Belleville washers function as locking devices in low dynamic load applications.

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.
