The design concept of the Philidas Turret nut is similar to that of the universally adopted Philidas Industrial nut where the locking function is provided by a slotted collar or turret section above the hexagon.
Whilst both types of nut have two slots, those on the Turret nut are positioned one above the other.
The metal above these slots is set to de-pitch the threads such that when the nut is tightened on to a bolt the thread is gripped on the flank ~ the point at which it is designed to take the thrust.
Special features of the Turret nut are lower prevailing torque than the Industrial nut, and higher re-usability. Further, it can be fitted to a male thread locking element first.
The all-metal Philidas Turret nut is suitable for use in high or low temperature conditions, and the locking performance is unaffected by oil, petrol or other liquids and vapours. It is easily assembled with hand or power tools, and will lock effectively either to a face or unsupported.
Standard finishes are zinc and chromate passivation or self colour for metric threads and zinc or self colour for other threads. Special grades of material, finish and design are available subject to minimum manufacturing quantities.
