Less effort, lower costs. Without the necessity of certain work steps – drilling, thread cutting, cleaning – and the optimization of tool sourcing, storaging and cycle times, the potential savings go up to 30 percent. Thus, it is no surprise you see a steady increase of thread forming screws on the market.

Direct screwing connection without additional thread cutting that connects components safe and long lasting becomes possible due to the function of the EJOT ALtracs® Plus. Without the necessity of cutting a thread reduces tool costs and working time.
Thinner, lighter, better connected. EJOT ALtracs® Plus screws can be found, wherever light metals need to be connected process reliable, fast and economically.
There are many good reasons for using our products.
Strength and options.
Point by point.
The optimized EJOT ALtracs® thread geometry makes it allows usage of smaller and shorter screw dimensions without cutbacks in strength.
Lower loss of preload force. Withstands even high dynamic and thermal stress.
Even without the usage of additional safety elements the connection is extremely vibration resistant.
High assembly safety. Thanks to low furrow torque, automatic screwing becomes even more convenient.
Multiple repeat screwing possible. Additionally, metric screws can be used in case of service or repair.
Compared to metric screws, specific work steps during the assembly process of the EJOT ALtracs® Plus screw can be left out. This leads to a reduction of the overall process and a more economical assembly becomes reality.
With a screw flank angle of 33° instead of 60°, the EJOT ALtracs® Plus achieves a higher connection strength, as it geometrically increases the load capacity of the nut thread. The smaller displacement volume of the 33° flank causes lower insertion torques.
A flat load flank of 22° causes a large axial force component (preload force) and a low radial stress. The 11° back flank prevents premature failure of the thread flank at high preload forces. The tooth root reinforcement provides a stable connection of the thread flank to the screw core.
During the assembly EJOT ALtracs® Plus forms a thread, which can be reused for metric screws. Should a repair or service be required, conventional screws can be installed without any difficulties.
The large flank coverage results in higher pull-out forces. The circular contact surfaces in the thread result in higher self-locking and thus a higher screw-locking function. Because more thread flanks are in use, the acceptance of drill hole tolerances is higher.
The EJOT ALtracs® Plus furrows a backlash-free nut thread in light metal. Paired with the geometrically strengthened nut thread tooth and the effect of work hardening during thread forming, a high load capacity of the screw connection is achieved, even under thermal stress. In addition, the formed EJOT ALtracs® Plus thread achieves a high dynamic safety due to the effective clamping torque, without additional measures such as polyamide coating, micro-encapsulation or under-head profiling.
The EJOT ALtracs® Plus offers the following characteristic values:
The design of the ALtracs® Plus thread geometry results in optimal utilization of the material properties.
Unlike other thread cross-sections, the ALtracs® Plus thread is fully engaged and fully loadable on its circular circumference.
