18-8 Stainless Steel Machine Screw 1/4"-20 Threads for Industrial Use

Product Description

The 18-8 stainless steel machine screw has a round head with a one-way slotted drive, is made in USA, and meets American Society of Mechanical Engineers ASME B16.6.3 specifications. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The one-way drive has a sloped S-shaped slot that enables installation with a standard slotted driver but resists tampering by requiring a special tool for removal. The round head has a domed shape. 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.
