Polymate20 Screw - Thread Forming Screws for Plastics

is a special fastener designed for reliability and an easy direct assembly into thermoplastics. Enhancement when compared with Polymate30: The re-designed geometrical flank allows for optimized movement of plastic material while initiating the fastening procedure. Under static and dynamic stress, a considerable increase is ensured in the service life of the joint. At the same nominal diameter, up to 50% gain in torsional and tensile strength. As there is a larger core and reduction in the thread pitch length, shorter fasterners and/or smaller diameters may be used. Improved pitch provides added vibrational safety. SOMETIMES SMALLER IS BETTER The visuals below show the advantages of a reduced fastener length and diameter by comparing Polymate30 to Polymate20. Substitute A provides a reduction in length, whereas Substitute B provides a reduction in diameter. For both scenarios, the reduction in pitch from the Polymate20 provides a maintainted thread flank.
