MilSpec: Military Specification


MIL-SPEC: Military Specification

Knowing whether certain parts or materials can stand up to extreme pressures is often an essential factor in making a purchasing decision. You may have noticed the term MIL-SPEC or (informally) mil spec or MilSpec in many different markets and niches, but what does it mean, and are MIL-SPEC products worth the additional cost?

Read on as our team at Greenshields Industrial Supply in Everett, WA, provides some explanations.


What Does Military Specification or MIL-SPEC Mean?

MIL-SPEC, or military specification, refers to any product or component that meets military specifications or standards. It stems from the U.S. military, which standardizes most of its processes and components, leading to better reliability and compatibility between systems.


Other versions of the same principle include:

  • MIL-DTL: Defense detail specification
  • MIL-PRF: Defense performance specification
  • MIL-STD: Defense standard

A large reason why military specification hardware has become popular is that the U.S. government has the rights to the component’s design. This means that various companies can make and sell these connectors based on the original MIL-SPEC design and manufacturing process.


The advantage to consumers is that you’ll get exactly the same mil spec connector with the exact same functionality, regardless of manufacturer. It allows you to shop around and find the best-value product without worrying about poor-quality imitations.

A MIL-SPEC Shop You Can Count On

The term “MIL-SPEC” carries a lot of weight and implies quality and ruggedness. To achieve mil spec standards, equipment or components must undergo extremely rigorous testing for thermal tolerance and mechanical strength. In many cases, the standards the military requires are much higher than those of most commercial products, giving milspec-certified products a reputation for being tough, robust, and high-quality. 

 Obtaining MIL-SPEC certification is an extensive and comprehensive process. Even a basic 461F certification can take up to two weeks to complete and often costs $25,000 or more. Companies that provide true MIL-SPEC equipment have an investment in offering the best products available on the market.


Advantages of Buying MIL-SPEC Products

When buying components or hardware, it’s a good idea to invest in high-quality products. This is especially true of fittings and bearings that undergo a lot of strain in their daily operation. Buying mil spec wiring or fittings will give you the peace of mind that you’ve bought a part that will stand the test of time.


Consequences of Using Low-Quality Tools and Parts

Using low-quality components can save you money in the short term, but these products are more likely to fail. Commercial standards are much less rigorous, and it’s easier for manufacturers to produce sub-standard parts. Eventually, these parts will fail and leave you dealing with expensive and unnecessary repairs.


What to Look for in MilSpec Products

Many unscrupulous manufacturers take advantage of the term “mil spec” without actually having the right certifications. For example, it’s easy to find a mil spec lower parts kit, but it’s hard to know whether it has undergone the military’s certification process.

To ensure that you get high-quality, genuine mil spec components or equipment, you need to do your research first. A good way to tell a genuine product is by buying from a company that works with a defense contractor that supplies the military, as we do at Greenshields Industrial Supply.
