Keensert® Inserts Compared to Acme Threaded Inserts and Keysert® Inserts

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 NA0151

Acme also manufactures a complete line of Industrial Style Keylocking Inserts.
