Molded-in threaded insert
PENN Engineering Fastening Technologies
Thru threaded, knurled spacers, types STKB and STKC include a uniform knurl diameter which reduces the risk of sink marks. They are also available in varying lengths for injection molding assemblies.
ITB, ITC
Thru threaded inserts, types ITB and ITC include a pilot diameter and undercuts allowing the plastic to flow into grooves, providing high pullout resistance.
Type IBLC
Self-locking, blind threaded, type IBLC has deformed threads which lock the screw in place to resist vibration. The blind end protects the threads from plastic intrusion.
