Customized Galvanized Pan Head Thread Rolling Screw Triangle Thread Self Tapping Screw Process

A triangular thread screw (often trilobular or taptite) is a specialized fastener with a non-round, three-lobed cross-section, designed to form its own threads (self-tapping) when driven into pre-drilled holes, particularly in metal or plastic. The 60° V-shaped thread profile provides high resistance to vibration-induced loosening, excellent locking action, and higher strength due to work hardening.
