Aluminum: is a metal with composition properties that include durability, malleability and a notable weight to strength ration.  Aluminum is one of the most widely used manufacturing materials as a result of its easy machinability and resistance to corrosion. 


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


Special Flat Washers:  are non-spring/wave flat spacers that have been customized through material, diameter measurements and/or height (thickness).  Specials washers are most often defined by non-circular or notched qualities in their composition.  


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.
