Product Introduction Spiralock Corporation has re-engineered the standard (female) internal thread form and added a unique 30degree wedge ramp at the root of the thread. This unidirectional internal thread form, called Spiralock®, mates with standard 60-degree male thread fasteners. The wedge ramp allows the bolt to spin freely relative to the female threads until clamp load is applied. At that point, the crests of the standard male thread form are drawn tightly against the wedge ramp, eliminating radial clearances and creating a continuous spiral line contact along the entire length of the thread...

Things to Know About the Spiralock Thread Form MATES WITH STANDARD MALE FASTENER The Spiralock thread form is designed to mate with standard 2A/3A fractional, 4g6g or 6g metric or UNJ-MJ male fasteners. TORQUE/TENSION RELATIONSHIP The Spiralock thread form design creates a helical line of contact between the crest of the bolt threads and its 30-degree wedge ramp. In order to generate similar joint tension as compared to 60-degree threads, the Spiralock threaded joint generally requires 10% - 20% greater torque due to the redirecting of some assembly forces from an axial direction to a radial...

Things to know about the Spiralock Thread Form LOAD DISTRIBUTION Research studies performed by Lawrence Livermore National Laboratory, Massachusetts Institute of Technology and others have confirmed that the load carried by Spiralock threads is much more uniform than the standard 60-degree threads. Additionally, they show that the percentage of load on the first engaged thread produced with a Spiralock tap is significantly lower, 24% versus 64% with five thread engagement. Spiralock Thread Standard 60º Thread The uniform loading eliminates the load concentration at the first engaged thread, thereby...
