Spiralock: At the forefront of self locking threaded nut technology
For more than 30 years, industry has turned to Spiralock when it needs to keep critical and demanding threaded joints from failing. Spiralock’s wedge ramp thread self-locking thread technology adds a locking feature to tapped holes that prevents vibration loosening while still allowing standard external threaded parts to spin freely during assembly.
Self-Locking Nuts
Using Spiralock self locking threads eliminates the need for spring washers, toothed washers, thread locking sealants, adhesive patches, disk locking washers (Nordlock type), nylon inserts, cotter pins and all other types of thread locking devices.
What is Spiralock?
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.
