Spiralock Key Locking Threaded Inserts
Spiralock® Key insert fastener with self locking threads.
Spiralock® is a self-locking female thread form with a 30 degree wedge ramp at the root of the thread. The wedge ramp allows the bolt to spin freely until clamp load is applied. At that point, the crests of the standard male thread are drawn tightly against the wedge ramp, creating a continuous spiral line of contact along the entire length of the thread engagement.
The main benefits of Spiralock® include:
- Mates with standard male thread - Faster to assemble, reduced operator fatigue
- Free spinning - Wedge tightens as clamp load builds
- Reusable - No deterioration of lock feature
- Self-centering of male fastener - Pushed inward from all sides
- Radial load distribution - Lowers chance of shear failure
- Improved fatigue life - Load carried across all threads
- Resistant to vibration loosening -Eliminates radial clearance - no transverse motion
The Spiralock® fastener selection available at Rivetwise include: Hex flange nuts; Wire thread inserts; Self-clinching nuts; Molded & ultrasonic inserts; Made-to-order fasteners

This versatile and economical insert offers a variety of installation methods – thermal, ultrasonic, or pressed – for applications in wood, particleboard, plastic, and most soft materials.
All the benefits of Spiralock self locking threads, combined with a conventional key insert fastener.
Spiralock Post-Molded Threaded Inserts.
Designed to have plastic molded around them in the mold cavity.
Spiralock Post-Molded Threaded Inserts
Ideal for use with plastic, threaded inserts from Spiralock provide superior torsional and pullout properties.
Spiralock Ultrasonic Threaded Inserts for Tapered Holes designed for use in tapered holes, which allows for rapid and accurate alignment prior to installation.
Our metric size Stainless Steel Hex Flange Nuts are made of Grade 316 austenitic stainless steel with exceptional corrosion resistance in many aggressive environments.
Spiralock Self-Clinching Miniature Fasteners fasteners effectively address vibration loosening issues in threaded joints, improving fatigue life and eliminating the need for other locking devices.
Spiralock Self-Clinching Blind Nuts provide an important barrier to protect threads against foreign matter and guard circuits from intrusion of extra-long screws.
Designed for use with all types of printed circuit boards, as well as acrylic, polycarbonate, and aluminum panels.
Self-clinching Floating Fasteners provide load-bearing threads in thin sheets and permit up to 0.030in (0.8mm) adjustment for mating hole misalignment.
Self-Clinching Flush Fasteners are designed to be completely flush in sheets or panels as thin as 0.060 in. (1.5mm).
Machined from a specialty stainless steel, these fasteners are heat-treated to create fasteners that are higher on the Rockwell Hardness scale than most 300 Series Stainless Steels.
Spiralock Self-Clinching Projection Weld Nuts provide load bearing threads in sheets too thin to tap and are designed for faster assembly.
