Spiralock Molded Thru-Hole Threaded Inserts

Rivetwise can supply you with the entire range of products from Stanley Engineered Fastening including the Optia Spiralock Molded Thru-Hole Threaded Inserts.

Spiralock Molded Thru-Hole Threaded Inserts

These inserts are designed to have plastic molded around them in the mold cavity. This process involves the placement of “core pins” into the minor diameter of the inserts prior to molding the plastic. Once the molding operation is complete, the “core pins” are removed leaving the insert encapsulated into the plastic.

The mold-in method offers better adhesion of plastic to the insert thereby providing higher torsional and pullout properties than most secondary operations.


  • Designed to have plastic molded around insert.
  • Superior torsional and pullout properties.
  • For softer materials. Ideal for use with plastic.
  • Made to order. Available in brass or stainless steel.
