Spiralock® offers a broad line of products for a wide range of applications, including fasteners, cutting tools and thread gauges.
It's the details that matter
For more than three decades, various industries have been using Spiralock® when critical and highly stressed threaded connections are required. The connection of male and female threads by means of Spiralock® unique self-locking thread technology reliably prevents loosening due to vibration while still vibration and still allows the unrestricted use of conventional threaded bolts. This effect is achieved by the special design of the internal thread.
