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...

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...

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,...

Self-Clinching Nuts – Metric Sizes These load-bearing threaded fasteners for thin sheets (Aluminum, Steel, and other ductile materials) have a clinching ring that locks the displaced metal behind the tapered shank ensuring high push out resistance. High torque out resistance is ensured when the knurled platform is embedded in the sheet metal.

Spiralock Wire Thread Inserts Tanged and Drive Notch (DN™) Spiralock wire thread inserts are helically-coiled fastening devices that provide permanent, wear resistant screw threads that exceed the strength of most parent materials; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear. Spiralock inserts are unlike any other wire thread insert for the fact that our inner diameter wire geometry incorporates our 30° wedge ramp thread form design.

Spiralock Wire Thread Inserts Tanged and DN™ Performance and Features Spiralock inserts are made of cold-rolled Type 304 stainless steel wire (AS7245), work-hardened to a tensile strength above 200,000 psi, having a hardness of Rc43-50. The finished surface (8-16 micro inches) is exceedingly smooth, virtually eliminating friction-induced thread erosion. It is important to select the proper insert length in order to balance the bolt tensile strength against the shear strength of the parent material. The insert lengths are calculated numbers because the inserts cannot be measured in the free...

Tanged and DN™ Wire Thread Insert Installation Instructions Step 1: Drill the hole Select proper drill size from the hole drilling specification chart (Table I). The Minimum Drilled Hole Depth is designed to allow for: the use of standard countersink as tabulated, the use of a Screw Thread Insert (STI) plug or bottoming tap, the use of standard installation set down of ¾ - 1 ½ pitch below work surface. Step 2: Countersinking Before tapping the hole, it is good practice to countersink the hole in order to prevent a feather edge at the start of the hole. Countersinking dimensions are listed...
