Heavy-duty key lock inserts are overall purpose threaded inserts with a heavy-duty thread thick wall, appropriate for most uses. Heavy-duty Key Inserts are perfect for thread strengthening, especially when the mating stud or bolt is often detached. They offer complete and permanent steel threads in almost any parental material –non-ferrous ferrous or non-metallic. Heavy-duty Key lock Inserts are also appropriate for rapid repair of damaged, stripped, or worn threads. Also, locking keys stop the insert from rotating.

Moreover, threaded inserts have locking keys to grip them in place. These inserts are primarily durable and are for metal applications, not suggested for cast iron or brittle substantial. It is essential for damaged restoration threads with an optimistic mechanical lock, stopping rotational spinout from vibration or torque.

Here are some facts about this versatile insert and some of the steps that will help you in installation. As well as this article will discuss the four basic locking styles.

Fast Facts:

  • It offers high strength and reliability.
  • Free-spinning bolt assembly.
  • No tang to break off after installation.
  • Significantly increases torque-down and load capability in weaker materials.
  • Preload locking with the application of torque.
  • Keys eliminate rotational movement of the insert within parent material.
  • Impossible to cross-thread during installation.
  • Hole preparation with standard drill and tap.
  • No special pre-winder, free-spinning installation.

How to Install

To install a key locking insert to renovation a damaged thread, follow these steps:

  • The first step of the keylock insert is to drill out the old thread with a standard drill and then get a new hole with the standard shrink.
  • The second step requires tapping the new thread with a standard tap.
  • The third step requires placing the insert by hand first and then using the tool to thread it down until it’s resting slightly below the surface.
  • The fourth step is positioning the installation tool so the hollows are not allied with the keys and, using a sledgehammer, tap the keys downward into the insert to save the installation.

To uninstall a key locking insert, drill out the material among the keys and the internal thread with a standard drill. Then, bounce the keys inner and break them off. You can then eliminate the insert using a typical screw extracting tool, and you can install a same-size replacement insert into the original hole.

Four Key lock styles

four basic key lock styles are;

  • Meager Wall – With an extra modest outdoor string size than the more normal inflexible supplements, Thin Wall implants are preferably suited for limited spaces where less draw-out forte is obligatory.
  • Rock-solid – As the typical key locking embed suitable for most uses, Heavy Duty inserts are generally supportive and have a thick and rigid string divider. These add-ons are outstanding for applications where you can eliminate the mating stud or bolt consistently.
  • Additional Heavy Duty – Extra Heavy-Duty inserts have a more protuberant outside string area. It gives a prolonged divider thickness, providing unique longer life, draw-out strength, and dependability. Their best use is with resources with lower extreme sheer power, which deliberates the most incredible draw-out stability and reliability.
  • Strong – These additions are great for moving lost stopping openings, openings, rescuing costly castings, or filling in places that are too huge.
