(more)We make Direct Tension Indicators, i.e., load cells, that assure compliance with bolting standards & specs. Torque, Turn of Nut, and TCs can all produce false positive tension, and regularly do: Torque scatter is ±40%, for new bolts, and worse for weathered. Relying on torque is optimism, at best. TCs are torque bolts that are adversely affected by cold or wet weather. Turn of Nut can be defeated by mispresenting turn angle, regardless of turn applied. DTIs read load. If a bolt is tight, a DTI will show it, independent of weather, torque, angle, tool, or skill.
