Hex Inserts

Hex Inserts are the industry standard for creating strong internal threads in mold-in applications. Machined from hex bar stock, they offer an excellent balance of strength, size, and cost-effectiveness.
The hexagonal profile provides superior torque strength while allowing resin to flow easily during molding. Machined grooves further enhance pull-out strength compared to post-applied or knurled inserts.
We offer a wide range of thread types including inch, metric, SAE, and NPT options, making these inserts suitable for both fastening applications and fluid/air connection points. This versatility ensures compatibility with diverse assembly requirements across industries.
