Diamond Wire Spring Company

What Diamond Wire Spring Company does

Diamond Wire Spring Company is a US-based, third-generation family-owned manufacturer of precision cold-wound springs and custom wire forms, founded in 1939 in Pittsburgh, Pennsylvania by metallurgical engineer Alphonse J. Fazio. The company designs and produces compression, extension, torsion, and die springs plus wire forms across a wire-diameter range of .008" to .750" — one of the widest in the United States — using CNC coiling, multi-axis wire bending, precision end grinding (to 3-degree squareness), and in-house finishing capabilities (powder coating, electro-plating, ArmorGalv, Geomet, passivation, shot peening, heat treating, e-coating). All three manufacturing plants (Pittsburgh PA, Tyler TX, Taylors SC) plus the Glenshaw PA catalog warehouse hold ISO 9001:2015 certification.

The company operates a dual revenue model. A catalog/e-commerce channel sells 10,284+ stock SKUs (roughly 1.5 million parts) on same-day or next-day shipping with tiered unit pricing and low minimum orders ($40-$60). A custom manufacturing channel sells engineered springs via an RFQ process with quotes typically returned within one business day, supporting OEM customers through blanket orders, scheduled releases, JIT, and Kanban inventory programs. Customers span at least nine verticals: electrical and power generation, rail and transportation, valve/actuator/regulator, agricultural and off-road equipment, shock and vibration control, oilfield drilling and mining, material handling, medical, and snow plow and trailer.

Diamond Wire Spring has remained under Fazio family ownership since 1939 with no external funding rounds or parent company. Current third-generation leadership comprises Chairman Donald Fazio, President Chris Fazio, and Executive Vice Presidents Frank Fazio Jr. and Kelley Christy (executive committee formed in 2019). Revenue and headcount (51-100 employees) are not publicly disclosed. The company serves exclusively US-based customers, with no disclosed international operations, and does not maintain AI/ML capabilities, public APIs, or disclosed patents.
