More About Part Number 538771

These 4-40 x 5/16" Thread Forming Screws feature a Flat 100 Head with a Phillips 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. Taptite style thread forming screws are designed to reduce driving torque while creating strong mating threads in ductile metals and similar materials. They feature a Zinc Finish, which provides reliable corrosion protection for general-purpose indoor and light outdoor applications while remaining a cost-effective choice for everyday fastening needs. A flat 100 head is designed to sit flush in a 100-degree countersunk hole, making it useful where a smooth finished surface is required. A Phillips drive features a cross-shaped recess designed for efficient installation with standard Phillips drivers and power tools.
