Further Information About This Product

Product advantages of these Fitsco threaded inserts:

  • The use of heat minimises the stress introduced into the boss
  • Heat installation provides high torque and pull-out performance for the threaded inserts
  • Easy to install threaded inserts by using heat staking or ultrasonics
  • Knurls facing opposite directions provide greater resistance in the plastic

Applications:

  • Hole Preparation: Moulded holes are recommended. The hole diameter is measured at the point where the bottom of the insert meets the moulded hole
  • Installation: The threaded insert is installed by either pre-heating the insert or the use of ultrasonics
  • Wall Thickness: An appropriate guide is that the wall thickness should ideally not be less than half the hole diameter
