Handling and maintenance
• The thread locking feature is integrated in the internal thread
• Modified profile with ramp surface in the direction of stress
• 30 degree ramp surface provides self-locking effect
• Easy assembly
• No assembly errors (forgetting the locking device) possible
• Use of standard external threads (screws) with tolerance class
“medium”
• Even distribution of stress over the whole thread length
• No stripping of threads
• Economically efficient locking system, no additional
components are necessary
• Undiminished holding power even under dynamic stress
• Repeated loosening and re-tightening without loss of function
• Internal threads can be produced with
Emuge
taps, cold
forming taps or thread mills
• Larger thread hole diameters, i.e. increased tool life for
threading tools
• Larger tolerances for thread hole diameters
Drawing standard
Whenever self-locking threads are required, this is shown on
the technical drawing. In the case of tapping through holes,
the arrow at the end of the center line illustrates the screw-in
direction of the bolt.
