About
Your Threaded Fastening Solutions Company
Spiralock® is a unique and proprietary preload locking internal (female) thread form that's exceptionally resistant to transverse vibration -- the primary cause of thread loosening.
Proven in thousands of applications, Spiralock threaded holes and nuts accept standard male fasteners, eliminate the need for other locking devices ... and substantially reduce the potential for fatigue failure when compared to standard threads.
Company History
Founded in 1927 under the name of Detroit Tap and Tool Co.. a manufacturer of cutting tools for the auto industry, Spiralock evolved over the years, tapping into new markets and industries with new types of products. The real breakthrough came in 1979 with the introduction of the Spiralock® internal locking thread form system. Successfully adopted by NASA on their space rocket engines, it soon became the choice of many of today’s engineers to prevent or solve screw threads from coming loose in a wide range of applications.
Headquartered in Madison Heights, Michigan, with operations in Europe, South America, and Asia, Spiralock serves a multitude of industries worldwide including aerospace, heavy truck, military, automotive, diesel engines, medical, farm & construction, oil & gas, and others.
