Greenslade & Company

What Greenslade & Company does

Greenslade & Company, Inc. is a privately held specialty manufacturer of precision fastener inspection equipment founded in 1978 by Joe Greenslade and headquartered in Fort Worth, Texas. The company designs, manufactures, and sells a comprehensive portfolio of dimensional measurement and inspection gages for the fastener industry — including external and internal thread gages (TRI-ROLL, X-180, X-120, Bi-Point, fixed limit ring and plug gages), recess and head gaging products (RecessCheker measuring system, penetration gages, TIR gages, wrenching and protrusion-height gages), and testing/dimensional measuring equipment (STF-250, CamberChek, DrilScruChek, Tru-Cntr, elongation and length gages). The portfolio is complemented by automated gaging stations (FASTATION, FinalChek) and proprietary Windows-based data collection software (N-SPEKT 2 and Gage Insite calibration management).

Greenslade operates an ISO/IEC 17025-accredited dimensional calibration laboratory through A2LA, providing NIST-traceable calibration services with a standard 10 business day turnaround and expedited options. Revenue is generated through three primary streams: (1) hardware sales of precision gages and integrated inspection stations priced via quote-based B2B sales, (2) recurring and transactional calibration services with software-based inventory management (Gage Insite), and (3) consulting services covering dimensional analysis, gage selection, training, and custom gage design. Customers are quality-control professionals in fastener manufacturing facilities, fastener distributors, and OEM manufacturers in automotive, aerospace, and medical device sectors. Distribution is direct via a website quote-cart system with an international representative network covering Brazil, Taiwan, China, India, and Germany; Greenslade also serves as the exclusive U.S. representative for TesT GmbH universal testing machines.

The company is owner-operated following the 2004-2007 transfer from founder Joe Greenslade to Larry Borowski (current President) and Larry McLaughlin. It holds more patents for fastener inspection devices than any other company it is aware of worldwide, including Patent #4,936,024 for the RecessCheker system, and has published over 100 trade journal articles providing problem-solving guidance to the fastener industry.

Broad incumbents

• Mitutoyo: Global leader in precision measurement and metrology with a wide portfolio of calipers, micrometers, and CMMs. Sells into many of the same fastener and component manufacturers as Greenslade, but as a broad-line incumbent rather than a fastener specialist.
• Instron (Illinois Tool Works): Major manufacturer of materials testing and force/torque measurement systems used in fastener torque/tension and tensile testing. Competes with Greenslade's torque/tension testing equipment through much broader industrial testing portfolio.
• Zwick/Roell: European manufacturer of universal testing machines and force/torque measurement equipment for fastener and material testing. Directly comparable to Greenslade's TesT GmbH partner offering and competes for advanced testing equipment budgets.
• Starrett (LS Starrett Company): Long-established manufacturer of precision measurement tools, hand gages, and metrology equipment. Serves fastener manufacturers and industrial quality control with a broader portfolio than Greenslade's fastener-specific line.

Direct peers

• Insize: Manufacturer of precision measurement instruments and gages offering competitively priced mechanical and digital gages. Overlaps with Greenslade across thread, length, and recess measurement categories.
• Mahr Group: German precision measurement manufacturer offering dimensional metrology products (dial gages, optical/contact measurement) that compete with Greenslade's higher-end mechanical and electronic gaging solutions in industrial quality control.
• Fowler (Fred V. Fowler Company): Supplier of precision measurement tools including calipers, micrometers, and bore gages used by fastener manufacturers. Competes with Greenslade in dimensional inspection of machined components.
• Thread Check Inc. Supplier of thread gages, ring gages, plug gages, and thread inspection equipment in North America. Direct competitor in fixed-limit thread gages that Greenslade manufactures.
• OSG (incl. Vermont Gage): Cutting tool and fastener-related measurement company that owns Vermont Gage, a traditional supplier of thread gages and plug/ring gages. Directly competes with Greenslade in fixed-limit and variable thread gaging.

Others

• TesT GmbH: Greenslade's exclusive U.S. partner and manufacturer of universal testing machines and force/torque measurement devices. Adjacent — not a direct competitor — but its product line overlaps with Greenslade's torque/tension testing capabilities.
