FAQs

Our thread rolling machines use a constant hydraulic force at high pressures to ensure the form of any thread we make is fully realized. This cold-working process not only saves cost by eliminating material waste compared to cut threads, but also creates a smooth, work-hardened exterior which makes them stronger and longer-lasting. 

We provide a wide variety of industries with quality standard and customized threaded rods and machined products, including:

• Machine Center Manufacturing
• Marine Manufacturing
• Hydraulics Manufacturing
• Oil and Gas Industry
• Lifting Mechanisms
• Food Processing
• Tooling Manufacturing
• Aircraft Manufacturing
• Medical Device Manufacturing

Yes. See answer to previous FAQ: Does Keystone Provide Parts Complete?

Yes. All of our products are 100% U.S. sourced and manufactured.

The “Made in the USA” label indicates that all significant parts of a product are produced, manufactured, and assembled in the US. This label is regulated by the Federal Trade Commission.

Keystone is an officially certified Women-Owned Small Business (WOSB) through the U.S. Small Business Administration, making us eligible to participate in the WOSB Federal Contract Program.

Simply Contact Us. The time we need to review a quote depends on the complexity of the request. Most quotes will be provided within 24 to 48 hours. Quotes for complex custom items may take longer. 

We are ISO 9001 certified and are committed to consistently providing quality roll threaded products. We thoroughly test our products by performing in-process testing and inspection.

• Pitch diameter (measured over wires)
• Rockwell hardness 
• Internal pitch diameter 0.0001” graduation
• Optical comparator 50x magnification
• Lead accuracy 0.0001” graduation
• Calipers and calibrated tape measure
• Thread ring and plug gage
• Third-party standards testing as required

Keyalloy is the trademarked name that Keystone uses for our alloy heat treated roll threaded bars. Keyalloy is a 4140 alloy steel heat treated to the requirements of ASTM A193 / ASME SA 193 Grade B7, latest revision.

Hot dip galvanized bars are only available in products up to three feet in length. We do not stock any bars that are hot dip galvanized; therefore, a minimum plating charge would incur on all special orders.
