Collection: Inserts - Expansion - Press In - 303 Stainless Steel

8 Products in this selection
  • Use for cored or drilled holes in plastics. Designed to replace molded in inserts and threads in plastic casings. Also known as threaded inserts.
  • Material : 303 Stainless Steel
  • Easiest inserts to install - simply push into a pre-moulded hole.
  • Used with plastics or other materials. Material must be strong enough to withstand the expansion of the insert.
  • The insertion of the screw locks the external knurls into the wall of the hole.
  • Provides excellent thread durability but where maximum strength is required other inserts shown in this catalogue should be preferred.
