Thread Forming Screws (Metal)

Tri-Lobe Thread Forming PAN Screws

Tri-lobe thread forming pan screws combine a uniquely rounded triangular shank with a broad bearing head to cold-form internal threads in ductile substrates. The tri-lobular geometry significantly reduces the required drive torque while ensuring a tight, gap-free fit that eliminates the need for secondary lock washers. Equipped with high-torque drives to prevent cam-out, they are ideal for securing enclosures, automotive components, and sensitive electronic assemblies.
