More About Part Number 623283

These 4-40 x 5/16" Machine Screws feature a Button Head with a Six-Lobe Drive and are made from 18-8 Stainless Steel. Machine screws are uniform-diameter threaded fasteners commonly used with tapped holes or nuts in machinery, electronics, and general assembly applications. 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. A button head features a broad, low-profile rounded top that provides a smooth appearance and a larger bearing surface than many other low-profile heads. The Six-Lobe Drive offers increased torque transfer, decreased stripping and extremely low cam-out.
