Keyserts are solid, one-piece, key-locking inserts used to repair damaged threads or for use in original equipment. The Keysert locking keys provide a positive mechanical lock that prevents rotation due to vibration or torsion. Keyserts are available in carbon or stainless steel, both in inch and metric series. Thinwall, heavy-duty, extra heavy-duty, and solid insert styles are available separately or in kits containing a range of sizes. Installation tools are also available separately or in a range kit.
