United Steel and Fasteners

United Steel & Fasteners is an Itasca, Illinois-based manufacturer of hot-forged steel fasteners, founded in 1975 and holding ISO 9001:2015 certification. The company operates three product divisions—Railroad, Industrial, and Waterworks—each targeting extreme-duty applications where structural integrity under high loads is critical. The Railroad division produces switch bolts, frog bolts, track bolts, shoulder bolts, hook bolts, plow bolts, carriage bolts, track and boat spikes, screw and drive spikes, rail clips, and rail pins. The Industrial division manufactures A-325 and A-490 structural bolts, anchor bolts, breakoff bolts, carriage bolts, elevator bolts, eye bolts, offset head bolts, plow bolts, step bolts, stud bolts, T-head bolts, track bolts, U-bolts and bend bolts, two-way and top lock nuts, nylon insert lock nuts, cap screws, lag screws, and solid button head and cone head rivets. The Waterworks division supplies flange bolts, track bolts, and T-head bolts in various materials for water infrastructure connections. Available alloys include 4140, 8630, and 4340 alloy steels, stainless steels, and nickel alloys. The hot forging process produces superior grain flow that eliminates voids and maximizes durability under extreme load cycles, enabling large complex forged shapes that outperform cast or fabricated alternatives. United Steel & Fasteners serves oil and gas, power generation, defense, mining, heavy industrial, railroad, and waterworks sectors.
