316 Stainless Steel Machine Screw, Plain Finish, Pan Head, Phillips Drive, 3/8" Length, #4-40 Threads (Pack of 25)

The 316 stainless steel machine screw has a plain finish and a pan head with a Phillips drive. The 316 stainless steel grade provides strength and offers better corrosion resistance than 18-8 stainless steel, especially in marine 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.
