Military Spec Socket Screws

Military spec socket screws, or MS socket screws, are a designation of fasteners that meet extremely strict standards and specifications established by the United States military. Military spec hardware is made from high-quality materials and is engineered to exact tolerances, ensuring consistent performance and reliability. MS socket screws feature a cylindrical head with a recessed socket that allows easy and secure installation with a hex key or Allen wrench. They are used in various military and industrial applications, including aerospace, defense, and marine industries, where durability, strength, and precision are essential. MS socket screws are also used in critical applications requiring high safety and security, including nuclear power plants and medical equipment.

Material & Finish Options for MS Socket Screws at ECS Fasteners

At ECS Fasteners, we distribute a wide range of military-spec fasteners manufactured from premium materials and precise specifications for high-performance applications. Our in-stock MS socket screws include fine and coarse threading options, with various material and coating options available.

300-Series 18-8 Stainless Steel – NAS1351/MS16996 & NAS1352/MS16995

18-8 stainless steel socket screws feature high strength and good corrosion resistance, containing 18% chromium and 8% nickel. While not as robust and corrosion-resistant as A286, 18-8 stainless steel provides a reliable, strong, and cost-effective material for military-spec fasteners, ideal for applications that don’t require the level of corrosion resistance that A286 provides.

A286 Stainless Alloy – NAS1351 & NAS1352

A286 stainless steel is a high-strength austenitic alloy with exceptional corrosion and heat resistance. A286 can maintain its mechanical properties at temperatures up to 1300°F (704°C). It also provides excellent resistance to oxidation, making it suitable for use in gas turbine engine components, exhaust systems, and heat exchangers. A286 socket screws are commonly used in aerospace and industrial applications requiring high strength and exceptional corrosion resistance. The alloy's unique combination of properties, including strength, durability, and heat resistance, make it an ideal choice for demanding applications.

Cadmium-Yellow Finish – MS16997

Cadmium-yellow MS socket screws are coated with a layer of cadmium and then treated with a yellow chromate conversion coating. The cadmium coating provides several advanced benefits, including outstanding corrosion resistance, high electrical conductivity, and low friction. Cadmium also has a high melting point, which allows cadmium-yellow-coated fasteners to maintain their properties at high temperatures. It should be noted that cadmium is a toxic material, and the use of cadmium-yellow fasteners is restricted in some applications. However, cadmium coating is utilized in military-grade fasteners for approved applications where other coatings cannot easily replicate its unique properties.
