Roll Formed Headless Fasteners by Hanger Bolt & Stud Co.

In business since 1967, Hanger Bolt & Stud Co. is an industry leading manufacturer of premium quality headless fasteners. We utilize a roll forming process that heat-hardens the metal material while maintaining its natural grain and molecular structure, giving our SAE, metric, and ACME threaded fasteners superior strength, durability, and wear performance. From tight-tolerance wire drawing to forming the finished product, we have the manpower and equipment to maintain strict control over the manufacturing process to ensure your custom fasteners are delivered on time, on specification, and on budget.

In addition to fully threaded and plain center hanger bolts, dowel screws, and rail bolts, we offer single-ended, double-ended, and fully threaded studs as well as smooth body and knurled pins. Constructed from carbon steel, brass, aluminum, and stainless steel, they are available in sizes from 4-40 to 0.5″ in diameter and up to 6.0″ in length for continuous thread versions and up to 40.0″ in length for double-ended thread versions. Our roll forming process is oil-free and leaves the fasteners with a clean, smooth finish.

We manufacture all of our products according to the Industrial Fasteners Institute standards and strict quality tests guarantee their integrity. Competitively priced, our custom fasteners offer a “Made in the U.S.A.” solution, ideal for large orders of 5,000 or more with 2-3 weeks lead time. Highly attentive to our customer’s needs, we are deeply dedicated to providing total satisfaction.
