PennEngineering - Molded-in Threaded Inserts, Self-Locking, Blind Threaded - Unified

CAD (0) ▾

Deformed threads create prevailing torque locking feature to prevent screw loosening due to vibration.
Blind-end protects the threads from plastic intrusion.
Stainless steel inserts offer lead-free alternative.
