L.S. STARRETT COMPANY (THE)

L.S. Starrett Company specializes in the precision manufacturing, inspection, calibration, and repair of high-tolerance measurement fixtures and gaging systems used in aerospace and defense applications. Their technical expertise centers on the fabrication and maintenance of alignment fixtures, v-gauge assemblies, and precision test equipment critical to aircraft component validation and quality assurance. The company demonstrates deep proficiency in metrology-grade processes, including dimensional inspection, fixture reconditioning, and calibration of specialized tooling to military and aerospace standards. Their work supports mission-critical systems requiring micron-level accuracy, with a focus on maintaining the integrity of inspection hardware used in aircraft assembly and avionics testing. The contractor has established a consistent relationship with the Department of Defense, delivering precision gaging solutions and test evaluation services across multiple branches. Their work supports aircraft parts manufacturing and maintenance programs, often involving complex fixtures used in production line validation and quality control cycles. These engagements reflect a trusted partnership where reliability, repeatability, and adherence to strict engineering specifications are paramount. L.S. Starrett’s industry focus is rooted in the manufacturing and maintenance of precision measurement equipment, primarily under NAICS 336413 for aircraft parts and 811210 for electronic and precision equipment repair. They serve as a niche supplier to defense aerospace supply chains, bridging the gap between high-volume production and the need for calibrated, traceable measurement tools. Their market positioning is that of a specialized precision engineering partner, not a general contractor. As a small business structured as 2L and based in Athol, MA, L.S. Starrett operates with a focused, technically driven model. While they hold no formal government certifications, their long-standing reputation in metrology and precision tooling, combined with consistent DoD contract performance, positions them as a reliable source for mission-critical gaging solutions within the defense industrial base.
