The favourable hole diameter is usually at the ratio. All epds are available as pdf for download at the website of the. 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. For these difficult conditions ejot has developed the innovative plastic insert solution deltasert p which, combined with the ejot delta pt screw, facilitates process reliable fastening.
Furthermore, you can download the latest product brochures, technical publications and the ejot company standards. A plastic delta pt p screw with similar dimensions weighs up to 85% less than its counterpart made of steel. Design recommendations for ejot pt screws use of the ejot delta pt for very high strength materials with high torques fasteners for plastics boss design the maximum clamp load is the criterion for the optimal boss design. Ejot delta pt is a threadforming screw for plastics and is especially suitable for thermoplastic materials. Ejot offers a broad range of innovative fastening solutions for the automotive, telecommunications, and consumer electronics industries, among others. It meets the highest demand on precision and reliability as well as offering significant application advantages, for example for the design support with the ejot delta calc prognosis programme. Pt products industrial fasteners division ejot industry. The torque can be documented with the assembly unit. The delta pt screw is the result of this optmisation process.
These grooves are pronounced at the screw point and taper off towards the screw head. Pt wn 1451 k2510 a2k mmax0,45nm 10% mmax0,4nm 10% to. Ejot saphir jt4 fasteners now with standard imperial equivalent sizes. Delta pt ds products industrial fasteners division.
Easyboss v products industrial fasteners division ejot. The ejot application engineers support you directly on site. The precondition for a reliable screw joint is the functional design of the components. As a rugged fastener it delivers superb performance, even under extreme. These grooves are pronounced at the screw point and taper off towards the screw. The ejot delta pt screw is a special fastening element for reliable and easy direct assembly into thermoplastic.
For that reason ejot developed a delta pt screw made of plastic, which fulfills these increased demands. Delta pt p products industrial fasteners division ejot. Ejot pt and delta pt screws for plastic applications. The following screws are tested to fix the pcb to the module. This innovative fastening element made of the thermoplastic ppa gf50 with 50% fibre glass, offers the same joint reliability as metal screws but with a much higher potential for weight reduction. The flowpoint delta pt screw combines two successful ejot methods in a unique new way. The specially adjusted delta pt thread offers the best conditions for. Ejot eppsys d products industrial fasteners division. There is a 50% higher tensional and torsional strength and a smaller thread pitch. Even optimisations such as a larger screw diameter, wall thickness increase or increased installation depth are only partially suited to solve this problem. The thread form ds duroset is the key for the solution of these difficult fastening challenges.

The agreement allows pennengineering to use ejot technical information, patent rights, and trademarks in connection with the manufacture and sale of pt and delta pt screw products. For the ejot delta pt ds screw special grooves are applied to the established delta pt thread geometry, which enable optimal forming of the female thread. The successful delta pt screw has been further developed the delta pt has an optimum geometry which favours the working of the plastic during the screwing process, and which reduces the damaging generation of heat. Optimum component design the layout design for the direct assembly of steel screws into thermoplastic material often shows that unreinforced materials such as pa6, pp, abs or pom often have considerably lower strength properties than. With two different standard versions clamp thickness 0.
