What is the Mil-Spec Dowel Pin MS16555?

The MS16555 is a stainless steel, cylindrical, solid, and headless fastener. The MS16555 is classified as a Mil-spec fastener, made to a specific exacting standard that defines in detail, the screw’s attributes, including: dimensions, tensile strength, hardness, threads, drive type, material qualities and plating, just to name a few.  Mil-spec is the informal name for the military standard the U.S. Department of Defense uses in the production of military equipment. Mil-spec fasteners are usually designated by an AN, MS, NAS or NASM prefix followed by a part number.  Each of these prefixes is an abbreviation: NAS stands for National Aerospace Standard and MS stands for Military Standard.

Dowel Pin Uses

Dowel pins are broadly used in various applications, including aerospace, electrical motors, hydraulic equipment, instrumentation, and more.

They’re used as a hinge, shaft, or pivot, and are used to locate or hold parts together within a precision assembly or a fixture, often when things are moving within that assembly.
