More About Part Number 604906

These 4-40 x 5/16" SEMS Screws feature a Pan Head with a Six-Lobe Drive and are made from 18-8 Stainless Steel. SEMS Screws are pre-assembled screw-and-washer fasteners designed to simplify installation, reduce handling time, and help prevent lost components during assembly. Square Cone Washer SEMS Screws use a formed washer that helps distribute load while providing a spring-like locking action in assembled joints. They feature a Plain Finish, meaning no additional surface coating has been applied; this is commonly used where the part will be painted, plated, or used in controlled indoor environments. The Pan Head features a slightly rounded top with a flat bearing surface, offering a versatile profile commonly used in sheet metal and general fastening applications. A Six-Lobe Drive offers increased torque transfer, decreased stripping, and extremely low cam-out.
