Thread Rolling: How it’s Done, and What Makes it the Best Choice

Since 1920, Keystone Threaded Products has manufactured the highest quality roll-threaded products available.  Thread rolling, which is the most common process of thread forming, offers numerous advantages over the alternate method of cut-threading.  These advantages include cost-savings in both raw material and overall manufacturing, improved thread strength and consistent quality.  Rolling is also a faster process than cutting.   Cold working of the material during thread rolling makes the threads stronger and more fatigue-resistant than cut threads.

Chances are, you’ve been in contact with threaded rods as their applications are vast.  For example, your favorite roller coaster is secured to the ground using anchor bolts.  The orchestra pit at the theater is raised and lowered using threaded rods.  Your car, truck or camper may have a screw jack.  Water control systems, heat exchangers, gates, mines, satellite trucks, even coffins have threaded rods as components.

Whichever application and product you need, we are confident you will be thrilled with the quality of our manufacturing.  We’d love to discuss thread rolling in more detail. Please feel free to check out our website, or give us a call at 216-524-9626 for more details!
