Thor Precision

What Thor Precision does

Thor Precision LLC is a privately held precision manufacturer of gas turbine studs, fasteners, rotor bolts, and nuts, founded in 2009 and headquartered in a purpose-built, climate-controlled facility in Greenville, South Carolina. The company specializes in high-precision rolled-thread applications, multi-axis CNC machining (up to 144-inch turning lengths), 4-axis EDM, deep hole drilling and honing, reverse engineering via CMM and vision scanning, and NDT Level 3 inspection (radiography, magnetic particle, liquid penetrant, ultrasonic). It holds proprietary IP covering part design, raw material selection (Inconel 625/718, Alloy A286, L605, Waspaloy, 422 stainless, B-16), surface treatment, and testing processes, with parts manufactured to its own drawings and interchangeable with OEM components for legacy and current-model gas turbines including GE Frame 3, 5, 6, 7, and 9 series, as well as F-class turbines.

The company operates on a quote-based, custom-manufacturing business model, selling one-time replacement parts directly to enterprise customers in power generation (utilities), MRO service providers, turbine OEMs, and — since a 2017 capability expansion — aerospace and defense. Sales are direct via phone and the company website; approved supplier status with major OEMs (Doosan, Ethos Energy, Sulzer, PSM) and AS9100-D, ISO 9001-D, DSQR, and NDT Level 3 certifications underpin customer trust. Plating and surface treatment are delivered through technology partners.

Since 2020 Thor Precision has operated as a subsidiary of PowerParts Group alongside sister company STAR Turbine; PowerParts Group was acquired by JLL Partners in January 2026 as the foundation of an engineering-centric power generation components platform intended to grow via organic investment and strategic acquisitions. The company is led by a veteran management team with 140-150 years of combined industry experience across precision machining, NASA quality engineering, and advanced metrology.
