Superior Thread Rolling is ready to take on your toughest thread-rolling and precision-machining challenges.
During the rolling process, threads receive forging properties that help to greatly increase the material’s fatigue strength and the static loading at the root radius. Superior uses both two- and three-die cylindrical thread-rolling machines. Superior’s four massive Reed machines can roll threads with diameters ranging from 5/8 inch to 5 inches.

Consistent. Accurate. Resourceful
These machines, the largest of those used by the company today, have enough power to cold form or hot roll some of the toughest exotic materials at heat ranges exceeding 50 Rockwell. During its history, Superior has accumulated probably the industry’s most comprehensive inventory of thread-rolling dies. The company works diligently to keep these dies continuously updated and maintained.

Finished Precision Parts
At Superior, manufacturing is a rigidly controlled process converting raw materials into high-quality finished products. Superior purchases raw materials or uses customer-supplied stock. Manufacturing output includes bolts, pins, clevis parts, special actuator screw and nut assemblies, and special high-strength parts fabricated from various new alloys.
As the company strives to continuously update its manufacturing operations, Superior has installed modern CNC machining equipment. To assure improved quality and increased productivity, Superior relies on its in-house CAD/CAM computer and LAN to reduce lead times and improve quality. Using this technologically advanced equipment, Superior performs more manufacturing “Miracles” than ever before. Superior focuses on the machining and thread-rolling on nonstandard parts, especially high heat-treated machined parts. This process requires close attention to details, flawless manufacturing planning and flight-safety parts approvals.
Why Choose Rolled Thread (Versus Cut Threads)?
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. This process is also capable of performing non-threading operations such as burnishing, knurling and rolling of helical and annular grooves of various forms.
Advantages of Thread Rolling
- Significantly reduced labor times means lower costs for you.
- A rolled threaded bolt has a smaller body diameter, therefore it weighs less than its full-bodied counterpart. This weight reduction reduces the cost of the steel, galvanizing, heat-treating, plating, freight, and any other costs associated with the fastener that are based on weight.
- Cold working makes threads more resistant to damage during handling.
- Rolled threads are often smoother due to the burnishing effect of the rolling operation.
