Sannohashi

What Sannohashi does

Sannohashi is a Japanese manufacturer and designer of automotive bolts, threaded components, cold-forged products, and precision-machined parts, founded in 1918 in Tokyo and now headquartered in Yashio-shi, Saitama Prefecture. The company operates two principal product lines: high-function bolts (engine bolts, suspension pins, ball joint screw components, and EV/hybrid battery and motor parts) and precision cold-forged components (high-precision gears, warm/cold-forged mount parts, proprietary Catch & Tight and Chara-tight bolt systems, hot-forged suspension links, and chassis tight bolt systems). Underlying technology combines cold forging (cold headers), hot forging, and precision machining, with proprietary bolt-system designs that the company states account for approximately 80% of high-performance fasteners used in vehicles (~60-80 critical components per vehicle out of 3,000-4,000 total fasteners).

The business model is B2B direct sales to automotive OEMs and Tier 1/2 suppliers via long-term supply contracts; pricing is not publicly disclosed and operates through enterprise procurement channels. Sannohashi is privately held, family-controlled across four generations of the Nagashima family, and certified to IATF16949 and ISO9001. The company maintains 15+ manufacturing and sales facilities across Japan, the United States (Indiana, Tennessee), Mexico (Silao, Villagrán), South Korea (Busan), Thailand, Indonesia, and China (Ningbo), with named customers including Nissan, Honda, Mitsubishi, Subaru, Suzuki, Hino, UD Trucks, Isuzu, Komatsu, JATCO, YOROZU, UNIPRES, THK Rhythm, Envision AESC Japan, GKN Driveline Japan, and others. Approximately 40% of the ~500-employee group is based outside Japan, reflecting an international manufacturing footprint built primarily between 1995 and 2012 to support just-in-time delivery to customer production sites across NAFTA and ASEAN.
