Thinking Precision, Thinking Big- Keystone Threaded Products

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.

@0 feet long two ends to thread, 3 and a half tons of precision.

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.
Thread rolling dies create the thread form on the workpiece.

Multiple passes are needed to build the thread up to the proper dimensions.
HAldf a million pounds of pressure are imparted on the rolls to plastically move the steel of the bar into the thread form. Read the gage.

Obviously it takes knowledge, skills, and experience to apply half  million pounds to produce precision work.
Rich says that he's rolled larger bars, but the confidence that skills and experience and a great team to work with make precision manufacturing a great career.

Here’s another look at a finished bar. Precision does not necessarily mean tiny!
Just another point of view so you can see the size of the work.

Thanks to Betsy Minnick and the Team at PMPA member Keystone Threaded Products for showing us that “Precision” is not a synonym for “Tiny.”
