The off-white acetal machine screw has a pan head with a slotted drive. Acetal provides excellent wear and abrasion resistance, is a strong yet lightweight plastic, and resists corrosion. It also resists moisture for dimensional stability. 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.
