Steel or aluminium inserts designed to provide load bearing threads in thin sheet materials.

Key features and benefits

  • Can be used in very thin sheet materials from 0.50mm (.020").
  • Wide grip range provides a placing capability in material thickness ranging from 0.5 mm (.020") up to 7.9 mm (.312")
  • Splined body provides increased torque-to-turn resistance
  • over conventional non-splined inserts
  • Low profile head allows near flush seating without special
  • hole preparation
  • Large flange version provides a large bearing surface
  • which increases push-out performance
  • Reduced tail end diameter offers ease of hole entry
