Boss design for EJOT PT® Screws. The precondition for a reliable screw joint is the functional design of the components. Based on laboratory trials with models, . The optimized thread flank angle of the EJOT DELTA PT® screw reduces the radial stress compared to common 60° flank angles of sheet metal screws. The 20°. EJOT DELTA PT® is a thread-forming or thread-cutting screw for plastics, especially thermoplastics. Self-tapping fasteners for plastics are ideal for thin- walled.

Strong connections for lightweight construction. As a rugged fastener it delivers superb performance, even under extreme conditions of use.
Ejot PT® screws
The special thread geometry, which is the result of a thorough analysis of material displacement during thread-forming, allows the formed plastic material to flow off in an optimal manner.
Self-tapping fasteners for plastics are ideal for thin-walled, flat construction methods. Their use can lead to material savings and shorter injection moulding cycle times. Ehot into account the overall fastening costs for a component, self-tapping fasteners provide significant potential for savings. The enlarged core cross-section increases the strength of the screw so that high preload forces and tightening torques can be achieved even in high-strength thermoplastics.
In lightweight construction every gram counts. The large axial component allows the formed plastic material to flow off in an optimal manner. The design pf the thread pitch allows for good vibration resistance, effectively preventing the screw from working loose. The new core profiling has resulted in even greater djot 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 ejkt thread flank.

Contents Introduction Product benefits Detailed description Personalised design support More information. Reliable plastic threaded fasteners. Applications Self-tapping fasteners for plastics are ideal for thin-walled, flat construction methods. There are many good reasons for using our products. Minimal radial stress Small flank angles reduce radial stress, allowing for thin-walled construction methods. Secure hold A perfect fit, through optimised material flow during assembly.
Self-locking effect in thread The optimised pitch minimises the possibility of the screw working loose. Extended life Quick pg install but very durable, thanks to the use of heat-treated steel PT High tensile strength and torsional resistance The enlarged core cross-section increases the strength of the screw so that high preload forces and tightening torques can be achieved even in high-strength thermoplastics.
