Additional Machining and Finishing 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.
