Features

  • Locking helical inserts positively secure threaded fasteners using resilient internal locking threads.
  • These internal locking threads use self-locking torque to grip the fastener.
  • They have a tang / prong at the end of their body for ease of installation.
  • Precision Series Chrislynn locking inserts have stainless steel construction and generally conform to aerospace or military specifications.
  • Raptor Supplies also offers Chrislynn Precision Series 8-pitch locking inserts that have a pitch size of 8 threads per inch of insert.
  • Chrislynn rock solid internal locking inserts are of key locking type (positive mechanical locks) and have solid, one-piece construction with 2 or 4 locking keys for higher holding strength as compared to other inserts.
