ecosyn®-plast Screws vs. Thread Forming Screws

You’ve more than likely heard the ecosyn®-plast screw referred to as the screw for thermoplastics. But how does this screw stack up against other options? Allow us to offer you our analysis.

Designed to be utilized for all different types of thermoplastic elements, the ecosyn®-plast screw is another innovative product that offers a number of benefits, including a high durability under various conditions in a variety of applications. But the true value of the ecosyn®-plast screw becomes apparent when compared to thread forming screws.

With the use of ecosyn®-plast screws, material flow around the threads is improved and cracking in the parent material is less of a risk. The 30 degree thread angle is capable of penetrating the plastic material with ease, and the material then flows down the thread flank. The end result is positive contact between the thread flank and the plastic material.

So what about thread forming screws?

If you’re using a thread forming screw with larger angles, it has the opposite effect – pushing rather than penetrating the material. Once assembled, there is reduced contact between the flank and the plastic material. This results in higher stress and lower stripping torques, and not to mention a significant risk for cracks.

For the reasons stated above, the difference between the two types of screws is clear. The ecosyn®-plast is a more efficient and effective solution – and could make a world of difference.
