Applications/ Advantages Designed to form its own thread in thermoplastic materials. The 30° thread angle reduces the outward expansion of the material being displaced. The recessed design of the thread root enables more material to ﬂow into the area between threads. The depth of the thread pattern increases the fastener’s load carrying properties while resisting vibrations, thus resisting loosening.

DescriptionA spaced thread fastener with a head that has a gently rounded top, cylindrical sides and a flat bearing surface that is 90° to the screw’s shank. When compared to a Plastite®-alternative thread rolling screw, the PT®-alternative threads are wider and have a sharper angle. Furthermore,

the core of the shank has a reduced diameter between each consecutive set of threads. The point opposite the head is blunt.

Applications/ Advantages

Designed to form its own thread in thermoplastic materials. The 30° thread angle reduces the outward expansion of the material being displaced. The recessed design of the thread root enables more material to flow into the area between threads. The depth of the thread pattern

increases the fastener’s load carrying properties while resisting vibrations, thus resisting loosening.
