Stage 8 Locking Fasteners & Header Bolts
Stage 8 is not just a company specializing in making locking fasteners, it's a team of highly dedicated professionals, striving to provide fail-safe joint integrity for crucial applications for years to come. Celebrating over 30 years of excellence in manufacturing the world’s most efficient active mechanical locking systems, Stage 8 is a well-trusted brand and industry leader within the market. The company offers locking systems that avoid even a single degree of fastener loosening rotation and ensure considerably more breakaway torque in comparison to other locking systems.
The history of the company began in 1985 with a man named Bruce Bennett and his idea of creating a bolt that wouldn’t work its way loose, even under conditions of extreme temperature and vibration. Since then, Bruce had plenty of experience in not only providing locking header bolts to exasperated backyard mechanics but in making them perform for multiple industrial purposes. Stage 8 has supplied its highly efficient locking bolts to companies that make automobiles, locomotives, and earthmovers. Today, the manufacturer has 18 million locking systems installed in industrial and automotive applications, with no failures reported. Stage 8 proudly supplies Link-Belt Cranes, GE Locomotive, Caterpillar, Oshkosh, NASA, Ford Racing, Stolle Machinery, BAE Systems, and more.
For the most crucial fastener applications, Stage 8 technology has regularly delivered distinct increases in equipment availability and safety, as well as significant reductions in maintenance costs and equipment failures. Currently, the company's product line includes performance automotive, off-road, industrial, custom, railroad, and military locking fasteners, all of which are proudly manufactured in the USA. Regardless of application complexity, the fasteners are designed to keep critical bolted joints tight in the most severe operating conditions. They are heat treated and through hardened to ensure maximum strength and superior performance. All locking fasteners install quickly and easily without special tools and are available in U.S. and Metric sizes.
Stage 8 is very proud to be a member of Contingency Connection, the biggest grassroots motorsports marketing platform in America. The company is also an honored supporter of the U.S. military; it is an active participant of the Association of United States Army (AUSA), the National Defense Industrial Association (NDIA), and a proud member of the Defense Sustainment Consortium (DSC). Given the critical nature of fastener integrity as it applies to any military application, Stage 8 looks forward to supply fail-safe locking fastener systems for all current and future military needs. The company now holds 78 patents and trademarks, issued or applied for. All of the Stage 8 locking systems (Counter Bore, Abutment, Bridge, and Spindle Nut) have been used in a broad range of industrial applications with a 100% record of success. So, if you're looking for a locking fastener system that perfectly works for years to come, Stage 8 is the brand you can always rely on.
