Mil-Spec Fasteners

Mil-Spec, or military standard, is a standardization created by the U.S. Department of Defense that serves as a measuring device to ensure that certain requirements are met by government contractors. Mil-Spec materials must pass specific requirements before they can be used for government contract work. Mil-Spec fasteners are commonly used in the defense, government, marine, nuclear, and shipbuilding industries. 

To win a defense contract, you need to satisfy a wide range of requirements, but if you’re able to do the same high-quality work for less money, you’ll have an edge. Value Fasteners can help keep the cost of your project low by offering competitively priced, advanced quality military fasteners that meet all MIL-Spec standards.

Mil-Spec Hex Cap Screws

Hex cap military fasteners have a six-sided head and are specifically manufactured to meet or exceed military specifications. The washer surface under the head of the military hex cap screw also allows for increased sealing capabilities and tighter tolerances.  

Mil-Spec Hex Nuts

Military grade hex nuts are designed to be used in conjunction with military grade anchors, bolts, screws, studs, threaded rods and on any other Mil-Spec fasteners that are manufactured with machine screw threads.

Military Grade Machine Screws

Mil-Spec approved machine screws are used to hold parts together in a wide range of machines, electronics, engines and industrial manufacturing equipment. Military grade machine screws are generally threaded through preexisting tapered holes.

Mil-Spec Self-Tapping Screws

Military grade self-tapping screws can tap their own hole as it is driven into the material. These unique Mil-Spec fastener screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design.

Military Grade Drive Screws

A Mil-Spec drive screw is a standard screw that is manufactured from military grade materials and is characterized by its external threads. Military drive screws are used to fasten materials by digging in and wedging into a material when turned.

Mil-Spec Socket Screws

Military standardized socket screws are designed to be tightened and loosened with the help of an Allen wrench. Mil-Spec socket screws are ideal for applications that require a strong bolt in areas with limited access.

Military Grade Washers

Mil-Spec washers are specifically designed to evenly distribute military grade fastener loads. Military grade washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminum surfaces.
