Leading the fastener industry for over 50 years

R&R Engineering Company is a custom manufacturer of U-bolts and threaded wire forms established in 1969 in Summitville, Indiana. Founded by Ralph Amos, it was his goal to become the most modern, competitive, and efficient manufacturer of bent bolts in the United States. With a focus on quality, price, delivery, and customer service, R&R has been serving its customers for over 50 years.

One of the keys to R&R’s success is the company’s investment in cutting-edge equipment and technology that enables production of high volumes of square, round, and custom U-bolts quickly and accurately. By continuously improving operations, R&R has been able to tighten tolerances to help produce custom U-bolts, L-bolts, and J-bolts which can be used in a wide range of applications.
