Production Spring has developed a new JOINT LOCKING SYSTEM that maintains retention and clamp load of threaded fasteners significantly longer and better than other widely used methods, helping to prevent threaded fasteners from loosening.
We recognize some fastening joints (plastics, fiberboard, thermal) may condense during the tightening process. Similar marketplace related wedge ramp solutions fail in lower rate applications.
However, EVR-TITE, with combined lock-joint & wedge-root technologies, differs from other tightening methods by providing a continuously axial compressive load during the tightening process. Using EVR-TITE technology, the crest of the standard exterior threads draws tightly against the wedge ramp thereby eliminating all radial clearance and creating a continuous spiral line of contact between the internal and external crest. EVR-TITE is able to maintain 80% of its original clamp load.
