Thread Inserts China Manufacturer
Heavy-duty key-locking inserts are engineered for robust strength, resisting rotation and pullout forces. After installation, locking keys secure them in place through parent material threads. Available in inch and metric sizes, their stainless steel solid bushing maintains thread quality. No special tools needed for installation; standard taps and drills suffice. Pre-assembled self-broaching keys set the depth and prevent unintended rotation.
