CSG PARTS, LLC

CSG PARTS, LLC specializes in the precision manufacturing of mission-critical fasteners, passive electronic components, and mechanical subsystems for defense and aerospace systems. The company produces helical compression springs, blind rivets, plain rod bearings, variable resistors, thermoswitches, and electronic connectors—components essential to avionics, flight control systems, and weapon platform reliability. Their technical expertise lies in meeting stringent military specifications such as MS, NAS, and MIL-STD standards, with demonstrated capability in high-integrity material selection, tight-tolerance machining, and certified lot traceability for aerospace-grade parts. A key differentiator is their ability to deliver small-batch, high-reliability components under tight lead times, serving applications where failure is not an option. The contractor maintains a consistent and deep relationship with the Department of Defense, supplying engineered components across multiple domains including aircraft systems, radar assemblies, and munitions interfaces. Their work supports sustainment, modernization, and new production programs, with recurring engagements on critical spare parts and replacement components for legacy and next-generation platforms. Industry focus centers on the manufacturing of mechanical fasteners (NAICS 332722), passive electronic components (NAICS 334413, 334416, 334417), and precision mechanical elements like springs and bearings (NAICS 332613, 332991). This positions CSG PARTS as a specialized supplier within the defense industrial base, serving the niche but vital segment of embedded subsystem components that enable system-level performance and durability under extreme environmental conditions.
