What taylor-drake, robyn - 4198946650 does

Trulok is a privately held, family-owned manufacturer of precision measuring instruments founded in 1947 by Samuel Rinsler and currently directed by his grandsons Brian and Michael Hunkins. The company designs and builds mechanical and digital gages — including countersink depth and diameter gages, flushness gages, perpendicularity gages, hole diameter gages, head height gages, grip gages, and the proprietary Fastener Head Protrusion Measuring System co-developed with Boeing under D-11805 specification — used for dimensional control directly in manufacturing and quality processes. Its core technology is sub-micron precision mechanical metrology, supported by in-house calibration equipment including Heidenhain CT 6001 Certo (±0.1 μm), Pratt Whitney SuperMicrometer (.00002" accuracy), Formscan 6100 (±1 µ" accuracy), Brown & Sharpe Global Image CMM, and OGP optical video inspection, with all instruments calibrated against NIST-traceable standards.

The company monetizes its installed base through two revenue streams: direct and distributor-mediated hardware sales of precision gages, and recurring calibration and repair services performed in its El Segundo facility. Trulok serves aerospace structures manufacturers (Boeing, Airbus, Northrop Grumman, Lockheed Martin, Textron, Bombardier, BAE Systems, Embraer, Gulfstream, British Aerospace, Cessna) as its primary vertical, with fastener manufacturers (Alcoa, Lisi, Allfast, SPS Technologies, Air Industries, Fairchild, Hi-Shear, Huck) as a secondary vertical tied to aerospace supply chains, and selected penetration into automotive and medical device manufacturing. Distribution is handled through a global network of authorized resellers covering the US, UK, France, Germany, Brazil, China, and Japan, with aerospace-specialist partners including WESCO Aircraft, Pattonaire SAS, and Edgar Hausmann GmbH.

The firm operates from a single headquarters at 601 Lairport Street, El Segundo, California, with no disclosed subsidiaries, no external funding rounds, and no parent company. Marketing is conducted primarily through the company website, which provides technical resources, calibration documentation, and direct contact channels to sales and support. No public pricing, headcount, or financial disclosures are available, consistent with its status as a closely held family business now in its third generation of ownership.
