The 18-8 stainless steel machine screw has a plain finish and a pan head with a slotted drive, and meets American Society of Mechanical Engineers ASME B18.6.3 specifications. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly 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.
