UNC/UNF Inch key-locking inserts provide outstanding strength and resistance to rotation and pullout forces post-installation. Locking keys firmly secure them by engaging with the parent material threads. These inserts come in inch and metric sizes, with a stainless steel solid bushing design guaranteeing top-notch internal threads. Installation demands no specialized tools—standard taps and drills suffice for hole preparation. Pre-assembled self-broaching keys establish the correct depth and ensure steadfast resistance against unintended rotation.
