TAPTITE® & TAPTITE 2000®
This bolt is a high-efficiency fastener that allows for the self-thread forming for female thread, providing an excellent
anti-loosening performance, electrical grounding and significantly reduces assembly costs.
MAThread®
This functional bolt is capable of preventing any operational failure caused by cross-threading on its own. Its
MAThread design fundamentally prevents cross threading with its P-point guide and the rounded tip of the thread.
When fastened, this bolt prevents any fastening failure resulting from cross-threading while ensuring easier fastening.
TORX® & TORX Plus®
As an improved version of a star-shaped (★) TORX, this TORX has a special structure capable of delivering a
higher assembly torque compared to the existing products while reducing the risk of CAMOUT, in which the tool
bits slip out of the recess while fastening. Note: Fastening tool bits for TORX and TORX PLUS are not interchangeable.
PT® & Delta PT® Screw
This screw is intended for use in plastic materials only (with a threading angle of 30º) and provides excellent
assemblability because it is designed to sit on the target object in the most efficient manner when fastened.
