MS Pins

Military-spec pins are specialized fasteners manufactured to meet specific standards and requirements for use in various military, aerospace, and other demanding applications. MS pin styles include cotter pins, dowel pins, and slotted spring pins. Military-spec pins are designed to meet rigorous performance and durability standards, including resistance to corrosion, high temperature, and high pressure. These pins also meet specific dimensional tolerances, material specifications, and quality control standards to ensure that they can withstand the demanding environments and stresses encountered in military and aerospace applications.

MS Cotter Pins

Cotter pins, or split pins, are thin wire pins used to lock a bolt or clevis pin in place. Military-spec cotter pins are often used in heavy equipment to prevent bolts from loosening due to vibration or stress. Our MS cotter pins are available in 18-8 Stainless Steel with a plain finish.

MS Dowel Pins

Dowel pins are cylinder-shaped pins typically used to align two components, including machinery and tooling equipment in industrial and manufacturing applications, ensuring precise positioning and repeatability. They are also used in automotive engines and transmissions to align and secure various parts, including crankshafts, camshafts, and gears. Our MS dowel pins are available in 400 Stainless Steel with a passivated finish.

MS Slotted Spring Pins

Slotted spring pins are hollow, cylindrical pins with slots along the pin's length that allow for expansion and compression. They secure two or more components together, providing a versatile solution for correcting misalignment or reducing vibration. Our MS slotted spring pins are available in carbon steel with a clear zinc finish for enhanced corrosion resistance.
