Screws For Plastics 17. PLASTITE Screws Reduced hoop stress.The PLASTITE screw ’s TRILOBULAR™ design reduces dangerous hoop stress and the friction of root interference, which can frequently cause the bursting of thin-walled bosses. Better quality threads.The smooth burnishing action of PLASTITE thread-rolling screws eliminates the dangers PLASTITE TRILOBULAR™ Thread Forming Screws for Plastics. Download PLASTITE PDF For our latest fastener to hereponents, . The PLASTITE screw's TRILOBULAR™ design reduces dangerous hoop stress and the friction of root interference, which can frequently cause the bursting of thin-walled bosses. The PLASTITE 45 screw is designed to facilitate thread-forming herepressible plastics while providing high resistance to strip-out and pull-out. The single lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics.

Better quality threads.The smooth burnishing action of PLASTITE thread-rolling screws eliminates the dangers inherent in the use of thread-cutting screws . Design Engineering Guide SUCCESS THROUGH INNOVATION Screws for Plastic: How to select fasteners for plastic joints By Lokesh Kumar Chief Design Engineer . forming screw names are TP30, PT, Boss, and Plastite . However, there are numerous other variations as well. Figure 4. Single lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics PLASTITE 48 PLASTITE 48The PLASTITE 48 screw combines a unique TRILOBULAR™ body with a 48 thread profile to maximize performance and reliability.

form design provides full relief for easy driving and effective resistance to vibrational loosening. PLASTITE 45 screws provide wide differential between drive and fail torques for exceptionally easy drive tool adjustment. Screws are manufactured to nominal inch and metric diameters. Easy driving. Excellent holding power.
