  • Mil-spec machine screws are used to fasten machine parts and in other applications. They do not have a tapered tip; the entire length of the screw has a uniform diameter. Military-spec machine screws are made from stainless steel or steel with black oxide, with a cadmium yellow or plain finish.
  • Mil-spec nuts are paired with bolts to fasten materials in military, government, aerospace, automotive or industrial applications. These fasteners are made of steel, including stainless steel.

The military-grade screws are designed to meet National Aerospace Standards, and can be used to separate electronic and electrical components. Sockets come with a hexagonal head cap opening to be used with Allen keys and hex wrenches. Both fully threaded and partially threaded options are available.
  • Mil-spec washers can be used in aerospace, automotive, industrial and defense applications. They reduce the chances of a nut or bolt loosening. Types of mil-spec washers include flat washers, split lock washers, screw washers, internal tooth lock washers and external tooth lock washers.
