Why thread rolling

Thread rolling is widely accepted as the fastest and preferred method of economically producing uniform smooth, precise threads of superior physical qualities.  Thread rolling utilizes hardened steel rolls to produce external threads.  The working surfaces of the rolls have a thread form which is a mirror image of the thread to be produced.  In penetrating the surface of the blank, the rolls displace material to form the thread roots, and force the displaced material radially outward to form the thread crests.

Advantages of thread rolling:

Cold working of metal during the thread rolling process improves the thread form physical characteristics and mechanical properties.  When the material is rolled, the structure is deformed creating the thread and improving the surface hardness.  The increased surface hardness results in thread form properties that are superior to those of original material.

Roll threading also improves the finish of the threads.  Smooth flanks of rolled threads provide better surface contact with mating threads.  The burnished roots and flanks are free of chatter, tearing or cutter marks that can serve as a focal point or stress and starting point for fatigue failures.

Rolled threads maintain consistently closer tolerances and uniformity than a cut thread.  Thread rolling is unique in its ability to maintain accuracy of the original set up during long runs of high-speed production.  Tooling does not change appreciably during the life of the rolling dies; they do not wear like other types of threading tools.

Roll threading material is more eco-friendly by using less material than thread cutting.  There is less material used during thread rolling, which will reduce cost of the threaded rod and offer savings to the customer.

Who’s Capable of Doing More?

When choosing between companies to provide service, customers usually choose between a few key factors of the companies to see where they want to take their business.  Some of the major factors are usually location, customer service, and capabilities. The most important feature for many is capabilities. In any given area, there are more than likely many companies that can provide something similar to what you need done, and regardless of industry, good customer service is an ideology most companies live by. So it comes down to “what can this company do for me that the others can’t?”  That’s where we step in; Keystone Threaded Products is capable of more than our competitors.

custom_roll_thumbUnlike most of our competitors, we have the ability to thread rods up to 15 inches in diameter. Most other companies only have the capability to only go between 5/8 of an inch and under 15 inches. Depending on the size and weight of what you’re moving, most companies in this country can’t handle it –but Keystone can.  Not only are we capable of creating numerous variations of lengths, we also have the capacity to produce more at a fast pace. Recently one of our competitors turned to us to help with a project because they didn’t have the capacity to thread roll 39 in bars in house, but they knew we could.

Even more important than our capabilities is our dedication to making sure our products are made with precision and quality, which is why our products perform the in-process testing for Class 2G tolerances.  We want you to know that we are dedicated to meeting their needs on all levels. For your next roll threaded  project, let Keystone show what we are capable of doing for you.
