Keensert Threaded Insert

Acme Keylocking Threaded Inserts are often compared to Keensert® inserts. (Keensert is a registered trademark of Huck Patents, Inc). A product similar to Keensert® inserts is the Keysert® insert. (Keysert is a registered trademark of Alcoa Fastening Systems.) Another style of insert is the Heli-Coil® insert, which is compared on another page. All these inserts are used for thread repair or to bolster the strength of the thread in a parent material, like aluminum.Acme Keylocking Threaded Inserts, Keensert® and Keysert®-style inserts are easy to install with standard drills and taps. The inserts are threaded in by hand, without the need of a pre-winder tool. Accidental cross-threading is nearly impossible when using these Keylocking Threaded Inserts.When an Acme Keylocking Threaded Insert, Keensert® or Keysert® -style insert needs to be removed, the material between the keys is drilled out with a standard drill, the keys are bent inward to break off, and a standard screw extractor is used. If a removed insert needs to be replaced, the new insert can be placed into the original tapped hole.Acme can manufacture special Keylocking Threaded Inserts to meet a user's specific requirements.Acme's MS/NAS Style Inserts are produced to the following standards: MS51830, MS51831, MS51832, NAS1394, NAS1395, NA0146, NA0147, NA0148, NA0149, NA0150, and NA0151Acme also manufactures a complete line of Industrial Style Keylocking Inserts.The Acme AdvantageAcme manufactures Miniature, Lightweight, Heavy Duty, and Extra Heavy Duty types with Non-locking and Self-locking internal threadsAcme manufactures a full range of Inch and Metric sizes in coarse or fine pitch threadAcme offers Keylocking Inserts with metric internal threads and inch external threadsAcme inserts for specific uses are available in floating, blind end, solid, and cast-in configurationsAcme Industrial Style inserts can be purchased in bulk quantities or kitAll Acme inserts are made in the USAAll Acme inserts are DFARS compliant
