About 18-8 Stainless Steel Machine Screw, Plain
The 18-8 stainless steel vented machine screw has a plain finish and a cheese head with a slotted drive. 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 cheese head has a flat top, rounded sides, and a high profile that holds a deep drive slot for high driving force. The screw has been drilled through its length to allow liquid and gas to vent from the bottom of a blind tapped hole, and is often used in vacuum systems.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.
