48-2 Plastite Screws
48-2 Plastite screws are specially designed trilobular thread-rolling screws for use in plastics.
Maximum holding power
48-2 Plastite trilobular screws have a twin lead thread design offering quicker and more effective screw penetration into the substrate. They also have a deep and narrow 48 degree thread profile with extra wide spacing between threads. This thread profile improves thread-forming and thread engagement within the plastic. In addition these screws have a trilobular thread configuration which improves displacement of material into relief areas when driven into the plastic. This further increases the resistance to vibrational loosening forces. The higher quality internal theads produced by these specialized screws also reduces material failure and improves holding power in plastic materials. It also reduces stripping, pull-out and allows for repeated removal and insertion into the same tapped hole.
Easier to drive.
The three lobed design of the trilobular thead with full relief of the thread form takes advantage of the physical properties of plastics by allowing recovery and filling-in between the trilobular threading, thereby decreasing the effort required to insert the screw.
Many Styles and Materials
48-2 Plastite screws are available in
steel with the following head styles: flat head, pan head, truss head and hex indented washer head, drives: Phillips drive, 6-lobe drive and hex head, and with either a clear zinc finish, or black zinc finish or black oxide finish. 48-2 Plastite screws are also available in
stainless steel 18-8 and 410 with pan head, flat head and hex indented washer head and either phillips or 6lobe drives.
Because of the variations in grades and types of plastics available and specific usage requirements, it is highly recommended to determine the ideal pilot hole size for each specific application. For specifications of recommended pilot hole sizes click
