The length of the
threaded section is a fixed value.

Threaded Assemblies," SAE Technical Paper 770420, 1977, doi:10.4271/770420.
Threaded hole, which functioned as nut, was made on one end of the lower rod.
More accurate solution of nonuniform distribution of axial load between roots of real
threaded connections was reported by (Birger & Iosilevich, 1973).
The supply system has been purged of these non-threaded rings so turn them in and order new
threaded rings with NSN 5855-01-466-7891.
Since the whirling cutter speed is the determining factor in calculating the part rotational speed and the resulting part finish and cycle time, the cutter was modified so that a part with a
threaded length of 10 threads that would take 1 minute to produce on another machine, could be completed on the Tsugami machine in 20 seconds.
Threaded fasteners can face limitations in diesel truck engine applications, particularly those with high performance turbo requirements, as they can be susceptible to shock, vibration, loading, as well as thermal expansion and contraction.

threaded inserts provide strong, reusable metal threads in plastics to enable subsequent access to assemblies when required.
The 30[degrees] wedge ramp not only eliminates sideways motion that causes vibrational loosening, the company said, but also distributes the
threaded joint's load throughout all engaged threads.
When components loosen, rattle, or fail, the problem can often be traced back to the lowly
threaded fastener, a technology as old as manufacturing.

threaded access hardware, from PennEngineering Fastening Technologies, is now available with a patented "anti-cross-thread" design to help speed assembly, eliminate repairs, scrap, and warranty service associated with thread damage.
