3.What is the difference between hex and heavy hex jam nuts?
A jam nut is a thin nut primarily used as a locking device, run up against a full-height nut that has been tightened into place to prevent that primary nut from loosening. Jam nuts are not used as structural parts and are commonly not manufactured to meet any specific nut specification since their primary function is to prevent the larger nut from backing off the threads. They are also occasionally used for leveling purposes.
The two styles available for a jam nut are hex and heavy hex patterns. The biggest difference between these two is sizing. The heavy hex pattern has a larger width across the flats and corners and is slightly thicker in comparison to the smaller hex pattern. Due to its larger pattern, the heavy hex jam nut is likely to have a higher proof load in comparison to its standard hex pattern counterpart. However, because these nuts are typically non-graded, there are not any strength comparisons available between the two.
Imported hex and heavy hex jam nuts are readily available in plain finish and hot-dip galvanized conditions. Imported stainless steel hex jam nuts are also available. These nuts are not graded in any way as mentioned above and do not come with any form of certification documents. For graded and/or domestic jam nut requirements they can be custom manufactured.
4.What is the difference between a standard hex nut and a heavy hex nut?
A standard hex nut, also referred to as a finished hex nut, has a smaller width across the flats and corners compared to a heavy hex nut, and a heavy hex nut is slightly thicker than a standard hex nut of the same nominal size.
In fact, heavy hex nuts are exactly a 1/8” larger across the flats than a standard hex nut in all sizes, requiring a 1/8” larger socket or wrench to install. Also, heavy hex nuts have a higher proof load strength compared to a hex nut according to ASTM A563.
