18-8 Stainless Steel Machine Screw Plain Finish Pan Head Phillips Drive Meets ASME B18.6.3 1/2 Length Fully Threaded 1/4 -20 UNC Threads (Pack of 50) Size : 1/4 -20 - 18-8 stainless steel provides good corrosion resistance and strength - Phillips drive has an x-shaped slot that accepts a Phillips driver and is designed to prevent over-tightening - Pan head has a flat top and short vertical sides with a rounded top edge - Meets ASME B18.6.3 specifications - Plain surface has no finish or coating The 18-8 stainless steel machine screw has a plain finish and a pan head with a Phillips 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 Phillips drive has an x-shaped slot that accepts a Phillips driver and is designed to allow the driver to slip out of the head to help prevent over-tightening and damage to the thread or fastener. 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.
