You’re Correct Mel, but….
Manufacturing techniques may vary slightly from supplier to supplier, but torque/tension performance is typically specified and published by SAE or ASTM and should be the same, regardless of the manufacturer. Color of the nylon insert typically identified the manufacturer, and unless specified by the end user, additive torque or use of a lubricant is not necessary or desirable- torque is really a “quick and dirty way” to achieve target tension. Adding more variation on top of thread form, plating, wrench accuracy, nylon, etc. does nothing to help us hit that target. Torque angle is another story.
