Square Inserts

Square Inserts are engineered for mold-in applications that are more demanding than typical post-applied inserts and standard mold-in insert requirements. Their square profile delivers exceptional torque and pull-out strength, making them ideal for high-performance assemblies.
With multiple thread sizes, material options, and precision-machined groove designs, these inserts meet stringent requirements for strength and reliability. Four- and five-square designs with multiple flanges and grooves increase surface area for a stronger bond, reduce leak potential, and improve torque strength. Single and double-square designs enhance pull-out strength and optimize plastic flow during molding.

Square Inserts provide superior strength and reliability for molded components, ensuring secure threaded connections in critical applications.
