SI (Standard Inserts) Molded-In Inserts
SI (Standard Inserts) Molded-In Inserts are installed during the molding process, and the inserts are located in the mold cavity by core pins. The core pins are withdrawn when the mold is opened, leaving the inserts permanently encapsulated in the plastic section with only the threads exposed. Inserts installed during the molding process avoid the need for additional procedures or installation equipment. The molded-in inserts include blind threaded inserts (IBA/IBB/IBC), self-locking blind threaded inserts (ILBC), through threaded inserts ( ITA/ITB/ITC), and knurled inserts (STKA/STKB/STKC). Typical applications include electronics (wearables, smartphones, and hand-held devices), automotive, aerospace and defense, medical, transportation, industrial, and recreational equipment.
Blind Threaded, IBA™, IBB™ and IBC™ Inserts
The Blind Threaded, IBA™, IBB™, and IBC™ inserts protect the threads from plastic intrusion. The Aluminum inserts are ideal for lightweight designs. The Aluminum and stainless steel inserts offer lead-free alternatives.

Self-Locking, Blind Threaded IBLC™ Inserts
The Self-Locking, Blind Threaded IBLC™ inserts protect the threads from plastic intrusion as deformed threads create a prevailing torque locking feature to prevent screw loosening due to vibration. The stainless steel inserts offer lead-free alternatives.
Thru-Threaded, ITA™, ITB™, and ITC™ Inserts
The Thru-Threaded, ITA™, ITB™, and ITC™ inserts with a pilot diameter and undercuts allow the plastic to flow into grooves to provide high pullout resistance. The Aluminum inserts are ideal for lightweight designs. The Aluminum and stainless steel inserts offer lead-free alternatives.

Thru-Threaded, Knurled, STKA™, STKB™, and STKC™ Inserts
The Thru-Threaded, Knurled, STKA™, STKB™, and STKC™ inserts feature uniform knurl diameters that reduce the risk of sink marks. These inserts are available in varying lengths for injection molding assemblies. The Aluminum and stainless steel inserts offer lead-free alternatives.
