HELICOIL
®
Plus Free Running*
Every thread of the thread insert with precision-formed, rhombic profile is Free Running.
The result is an internal thread true to gauge that can be used from both ends.
The dimensional stability of the ISO thread complies with DIN 13 6H as well as for
special requirements with 4H and meets the demands on international standard
specifications.
The advantages of the HELICOIL
®
Plus system are particularly apparent with respect
to processing and tools and result in shorter cycle times.

Classic Screwlock*
This thread insert has an additional screw-locking area. One or several polygonal-
shaped threads clamp the flanks of the installed 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. However, the
prevailing torques can also be adjusted as required for the corresponding
application, e.g. for securing of setting screws.
HELICOIL
®
Classic Screwlock can only be used with screws of higher property
classes (8.8 and higher).
Common lubricants according to the manufacturers’ recommendations should be
used for highly alloyed screws.
