詳細介紹

Reliable plastic threaded fasteners

EJOT DELTA PT® is a thread-forming screw for plastics and is especially suitable for thermoplastic materials.

The EJOT DELTA PT® screw is a development of the PT screw, and the result of years of hands-on experience of screw fastening in thermoplastic materials. As a rugged fastener it delivers superb performance, even under extreme conditions of use.

Thread geometry

Compared to conventional thread flanks of tapping screws with a 60° flank angle, the optimised flank angle of the EJOT DELTA PT® screw reduces radial extension. The 20° or 30° angle generates only low radial extension, making thin-walled construction possible. The large axial component allows the formed plastic material to flow off in an optimal manner.

Flank geometry

Good resistance to vibration

The design of the thread pitch allows for good vibration resistance, effectively preventing the screw from working loose.

Increased dynamic load capacity

The new core profiling has resulted in even greater safety under dynamic loading. The fatigue strength of the screw is substantially increased by the enlarged core cross-section and the optimised thread profile. To further increase dynamic security, the thread ridge has been stabilised at the root to reduce the risk of flank breakage. The optimised pitch, resulting in an increased thread coverage, has also reduced the risk of fatigue fracture of the thread flank.
