More About Part Number 628563

These 5/16-18 x 3 1/2" Thread Forming Screws feature a Flat Head with a Six-Lobe Drive and are made from 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. Thread Forming Screws for Metal are designed to reduce driving torque while creating strong mating threads in ductile metals and similar materials. They feature a Black Oxide Finish, which provides mild corrosion resistance and a dark matte appearance and is commonly used in indoor or lightly protected applications. The Flat Head sits flush or countersunk with the material surface when fully installed, making it a strong choice for applications that require a smooth, low-profile finish. The Six-Lobe Drive offers increased torque transfer, decreased stripping and extremely low cam-out.
