The Team at Keystone Threaded Products shows us that “Precision” doesn’t necessarily mean “Tiny” as they thread the ends of some 20 foot long, 10 inch stainless steel bars for a Metalworking press. The thread is a 10-1/4″ : 4 UNJ RH applied to each end of the 3 and a half ton bar.
At Keystone, they roll the thread form onto the material which makes for a stronger thread. Alignment and following the process is critical to assure a good thread.
Multiple passes are needed to build the thread up to the proper dimensions.
Obviously it takes knowledge, skills, and experience to apply half million pounds to produce precision work.
Here’s another look at a finished bar. Precision does not necessarily mean tiny!
Thanks to Betsy Minnick and the Team at PMPA member Keystone Threaded Products for showing us that “Precision” is not a synonym for “Tiny.”
