More About Part Number 616530

These M4-1.75 x 20mm Thread Forming Screws for Plastics feature a Pan Head with a Six-Lobe Drive and are made from 18-8 Stainless Steel. Thread Forming Screws create mating threads by displacing material rather than cutting it, making them useful in softer materials where strong thread engagement is desired. These Thread Forming Screws are designed specifically for plastic, forming durable mating threads while helping reduce stress in the material. 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. The Six-Lobe Drive offers increased torque transfer, decreased stripping and extremely low cam-out.
