TAPTITE As a tri-lobular thread forming screw, the Taptite has mating threads that are work-hardened as they are developed. The tri-lobular shape of the screw causes the material to form around the screw during the process of elastic recovery, providing resistance to loosening caused by vibration, and most importantly, inherently providing resistance to vibrational loosening. Plastite screws were developed specifically for use in plastics.
A thread rolling screw (TRS) is a type of threaded fastener that utilizes threads to reliably and securely fasten different materials. These types of screws create threads in the material by forcing the material outward.Self-tapping trilobular thread rolling screws feature a specialist tip and thread configuration, which is designed to both bore and tap its own hole in one operation.
Pan heads are slightly curved with a low, large diameter and high outer edge. The large surface area enables slotted or flat drivers to easily grip and exert force onto the head. Pan’s heads are one of the most popular head types, recommended for most new designs to replace round, truss, or binding heads.
