Key Features
Trilobular Thread Design – The triangular cross section of the thread displaces material rather than cutting it, forming a smooth, work hardened internal thread while reducing driving torque.
No Chips, No Tapping Required – Eliminates the need for pretapping holes, reducing production steps and associated costs.
Vibration‑Resistant Joints – The cold formed thread creates a tight fit that resists loosening under dynamic loads, often eliminating the need for thread locking adhesives or washers.
Fully Reusable – Screws can be removed and reinstalled without compromising thread integrity, facilitating maintenance and repairs.
Case‑Hardened Surface – Heat treatment delivers a surface hardness of at least 450 HV0.3 with a core hardness of 290–370 HV10, ensuring excellent wear resistance and thread‑forming capability.
