Machining, Finishing, Bending Services
Additional Machining, Finishing & Bending Services
Custom threading equipment, turning centers, and screw machines at our facility allow us to machine as well as finish custom stud bolts. We have dedicated Traub automatic screw machines to produce stud bolts with diameters ranging from 1/4" through 2". These Traub automatics cut and chamfer parts in a single operation.
​
Three Brown & Sharps 2G automatics enable us to cut larger diameters with precision, speed, and accuracy. Utilizing custom-built threading machines, die heads, and holders, we manufacture quality fasteners to precise tolerances. Our Landis threaders ensure accurate threading on large diameter parts.
​
For high volume precision threading applications, we make use of Tesker Roll threaders. Thread quality is inspected at the production stage using ring gages and set plugs. Stud bolts can also be hot dip galvanized, passivated, or coated with black oxide/phosphate/zylan. In addition, we also offer custom packaging services to prevent shipping damage.

Surface Finishing
We offer a full range of protective and finishing treatments to enhance the performance and longevity of your parts. Our capabilities include passivation, plating and coating, and hot dip galvanizing, all designed to improve corrosion resistance and surface durability.
These finishing processes are ideal for extending product life in harsh environments and ensuring compliance with industry standards across a variety of applications.
Production Capacity
We specialize in short-run production with minimal lead times, making us the ideal partner whether you need a single prototype or a full run of 10,000 parts. Our flexible and efficient manufacturing process allows us to quickly adapt to your specifications without compromising on quality or precision.
From urgent one-off jobs to small- or medium-sized production runs, we’re committed to delivering fast turnaround times, dependable service, and consistent results every time.
Screw Machines
Our production floor features a robust lineup of automatic machines to handle a wide range of part sizes with speed and precision. This includes sixteen A-25 Traub machines, capable of running diameters from 1/4" up to 1", ideal for high-efficiency production of smaller parts. For larger diameters, we utilize three Brown & Sharpe 2G automatics, which handle material from 1/2" to 1-1/4" in diameter, offering reliable performance and consistent results on more demanding jobs.
Saws
Our in-house cutting capabilities are anchored by a WAGNER WA70 Cold Saw, known for its precision and reliability in high-quality material preparation. This versatile machine accommodates diameters ranging from 5/16" to 2-1/2" and cut lengths from 6" up to 40", making it suitable for a wide variety of part sizes and applications.
Whether you're preparing stock for small custom components or large production runs, the WA70 delivers clean, accurate cuts with tight tolerances and excellent surface finishes, reducing the need for secondary operations and improving overall efficiency.
Turning Centers
Our CNC turning capabilities are powered by a fleet of precision HARDINGE Conquest machines, built to handle complex parts with tight tolerances and repeatable accuracy. Our equipment includes a Conquest 51, capable of turning parts up to 2-5/8" in diameter and 22" in length, ideal for larger components and extended geometries.
We also operate two Conquest T42 machines, each handling up to 1-1/2" in diameter by 13" in length, perfect for mid-sized production runs. For smaller, high-precision work, our Conquest GT can machine parts up to 1" in diameter by 11" in length, offering excellent control for intricate details and tight specs. Together, these machines allow us to meet a wide range of customer needs, from small custom parts to high-volume orders.
