Military Spec

BW Industrial Sales is your source for all military hardware. During WWII, the USA and Britain had a strong alliance on the battle field which often lead to the sharing of tanks, aircraft, guns, and other machinery. Historically, American fasteners were not always interchangeable with British machinery and would have issues fitting the equipment properly. This sparked the standardization of United States Military Hardware. Any equipment manufactured for defense purposes must follow strict United States Military Standards, including fasteners.

MS Hex Cap Screws
