Founded in 1973, Interstate Threaded Products manufactures and distributes a portfolio of threaded products and custom fastening solutions for customers across North America. The company serves end markets including infrastructure, power generation, construction, telecommunications, industrial manufacturing and agriculture.

ITP’s product categories include all thread rod, all thread stud, anchor bolts, custom parts, eyebolts, J-bolts, keystock, nuts and U-bolts. The company describes itself as a single source for high-quality threaded fasteners, with a focus on accurate order fulfillment and timely delivery.

Rick Stone will continue to serve as President of Interstate Threaded Products and lead the company through its next phase of growth.
