The advantages:
L4022 Screwlock has the same advantages as L4020.
In addition, there is a screw-locking area. The screw is locked by one or several polygonal-shaped threads clamping the flanks of the screwed in screw. The elastically resilient frictional locking results in prevailing torques similar to the specifications of ISO 2320. These screw locking torques meet the demands of technical delivery terms regarding international standard specifications.
L4022 Tangfree Screwlock can only be used with screws of higher property classes (8.8 and higher). Common lubricants according to the manufacturers’recommendations shall be used for highly alloyed screws. This thread insert is widely used in the aviation industry.
