Recommended product: POWERLOK® locking screws
POWERLOK® screws are locking screws with a TRILOBULAREM® screw thread. They screw into an existing metric ISO thread (tolerance range 6H). Small 30° edges are rolled on the regular 60° thread edges, and these extend beyond the nominal bolt thread diameter. When the fastener is screwed into the counter-thread (ISO 6H), these 30° tips penetrate and cause the screw to self-lock, thus creating an oscillation and vibration-resistant seat. The deformation of the female thread caused by the 30° tips takes place in the flexible area. This ensures a high degree of self-locking and a reusability rate for the screw of up to five times into the same female thread. There is no possibility of lengthways or crossways movement between screw and female thread. Even in ductile materials, no signs of deformation occur. Even without head friction, the ARNOLD POWERLOK® thread guarantees a high degree of vibration resistance – a benefit when used as threaded bolt or setting screw.
