The stainless steel machine screw has a plain finish and a pan head with a slotted drive, is made in USA, and meets American Society of Mechanical Engineers ASME B18.6.3 specifications. Stainless steel resists corrosion and may be magnetic. The slotted drive has a linear slot for use with a flat-blade driver. The pan head has a flat top and short vertical sides with a rounded top edge.

Machine screws are threaded fasteners that are typically used with nuts or drilled and tapped (threaded) holes. Machine screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles, which determine the type of driver required to install and remove the screw.
