The Molded Thru-Hole Threaded Insert, part number 94425, from Stanley Engineered Fastening - Spiralock, features a unique self-locking thread technology designed to enhance the reliability of threaded joints. This insert is specifically engineered to be molded into plastic, which improves adhesion and provides superior torsional and pullout strength compared to traditional secondary fastening methods. The design incorporates a wedge ramp that engages during tightening, ensuring a secure fit that prevents loosening due to vibration. This product is suitable for a variety of applications across multiple industries, including aerospace, automotive, and electronics, where maintaining joint integrity is critical.
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.
