Firstly, the bolt load deformation standard is established by bolt calibration. Before the assembly, the bolt length measurement, recording and marking are prepared. Through a large number of tightening data statistics, the bolts near the minimum dynamic torque monitored by the bolt tightening ...
standard torque measurement techniques - giving the BG80 range accuracy within 0.0001mm (0.00001 inch). Using the gauge’s RS232 interface together with the optional shut off accessory the gauge can be programmed to automatically stop the tightening process when the appropriate load has been applied...

The method involves measuring the torque and angle of rotation produced at time of bolt connection tightening, and calculating a gradient with a screw drop specific dynamic threshold range based on the measurements. The screw drop specific dynamic cut-off threshold, which slopes down from the gradie...
Fewer, stronger jackbolts than any other multi-jackbolt tensioner makes NXT up to 30% faster to install, with an extremely accurate preload range of ±10% providing the same security while reducing installation and removal time. Laser markings clearly indicate the optimal tightening sequence.Easy...
