Thread tighteners - Import export

Press-In Inserts are designed to be pressed into a straight hole without melting the plastic prior to installation. Ideal for use in softer plastics, the helical knurls of the Press-In Inserts are used to provide both torque and pull-out resistance and to ensure good plastic flow as the Insert rotates into the hole. Installation torque to achieve sufficient tension between the threads is not a problem in that the helical knurls are designed so that the direction of the installation torque will have the tendency to drive the Insert into the hole — which of course is not possible — as the threaded joint is tightened. A pilot only slightly smaller than the hole and of sufficient length is designed to assure straight insertion into the hole. Press-In Inserts offer rapid installation with no specialized equipment and achieve good overall joint performance. If installation equipment is required, SPIROL also offers a standard comprehensive line of Insert Installation Equipment.

Hybrid Technology – Smart Assembly Solutions The YOKOTA electric system wrenches with integrated torque transducer and angle sensor offer a large reduction of energy consumption, a high degree of accuracy and fantastic work efficiency. Torque transducer and angle sensor located directly at the front of the main shaft, giving the best accuracy of measurement. Faulty tightening detection with maximum accuracy due to the use of an integrated torque transducer and also an integrated angle sensor. During the tightening process, four different variables are measured and monitored: Torque - Angle - Time - Nº. of Impulses. Torque transducer measures directly and transmits the signals contactless. Detects cross threads, double hits, contamination, etc. Special feature to prevent cross threaded tightening: reversely rotating a bolt to a preset angle at the start of tightening. Combinations of buzzers and LED (Green / Red) for operator feedback on OK / NOK tightenings. [...]
