From tightening large industrial bolts used in windmill gearbox assemblies to bolting maintenance applications for oil & gas pipelines and rigs, the Mountz electric torque multipliers achieve precision torque in a quick, cost-efficient manner. The electric torque multiplier shuts-off when pre-set torque is achieved. It’s a non-impacting and operates at a smooth, continuous rotation; the…
Generally, in the majority of applications, the reliability of the joint is dependent upon the bolts ability to clamp the parts together. Adequate clamping prevents relative motion between parts of the joint and leakage from joints containing gaskets. Measuring a bolts clamp force is difficult, especially under production assembly conditions. The clamp force generated by…
If in a plug-type screw connection the nut is gradually tightened more and more firmly, then the resistance increases steadily until a threshold is reached at which the screw begins to lengthen at which the screw begins to lengthen permanently. At this stage, even a weak force suffices to lengthen it even further. The tightening…
