How to Install Recoil Thread Inserts – Step-by-Step Guide

When using industrial fasteners, insertable threaded parts are important to repair stripped threads or reinforce threads in softer materials. Recoil thread inserts are particularly useful and used in industries-from car-manufacturing to aerospace-owing to their durability, abrasion resistance, and robust hold-the extension of their life through component elements.

Why Recoil Thread Inserts?

For instance, in industrial fasteners, recoil thread inserts especially where assembling and disassembling is frequent improve thread strength and durability. They prevent costly and sometimes well-timed replacement and loss due to the downtime they achieve by reinforcing threads in softer materials or repairing stripped threads.

Now, let’s go through the installation procedure of Recoil thread inserts.

Step 1: Choosing the Right Recoil Thread Insert

Recoil Thread Inserts are sold in a wide variety of diameters, materials, and configurations to meet the demands of an application. Be sure to use one that matches the diameter and thread form of the existing hole along with the material of the parent part. Inserts vary in length and pitch, and thus verifying these parameters will avoid installation problems.

Step 2: Prepare the Hole

When you are replacing a Recoil thread insert in a damaged or stripped thread, you might have no choice but to pilot drill out the hole so that you may clean out the remnants of the original thread. Either the diametrical pilot drill or the smaller pilot drill bit from the Recoil thread insert kit can be used. Do not over-widening the hole, as this will compromise the grip integrity on the insert.

Step 3: Tapping The Hole

Use the tap provided with the Recoil thread insert kit to tap the hole. You should tap so as to establish an acceptable thread profile which the insert shall be screwed into for secure holding.

1. Hold the tap perpendicular and aligned to the hole so that the new thread cut is uniform around.

2. Rotate it in a clockwise direction, offering gentle, consistent pressure so that it cuts the whole length of the hole.

3. Once you’re done, take off the tap and replace it. To take the tap off, simply turn it counterclockwise.

Step 4: Metal Shavings from Tapping

Mount the installation tool with the Recoil insert attached to it. When the tang, which is the small tab at the end of the insert fits over the tool, then the installation will go along just fine.

  1. Slowly push the insert into the tapped hole, orientating and keeping it in position.
  2. Wind the insert into the hole with a slow turning of the tool. This is going to compress slightly as it enters the hole. Be certain that it’s flush or perhaps even a little below the part surface.
  3. Have the installation tool screwed out after being positioned.

Step 5: Break Off the Tang

Remove the tang to expose the threaded path for the bolt. Place the tang break-off tool over the tang and, with a light, sharp tap, gently strike. The tang will snap cleanly off. It is important the tang be completely removed from the insert. Any portion of the tang remaining inside the insert can hamper the installation of the bolt.

Step 6: Test the Installed Insert

The newly installed Recoil insert must be able to have a bolt threaded in smoothly without resistance or looseness. If the bolt does not seat properly, then probably all the steps were not completed correctly.

Conclusion

With this guide, you can successfully install Recoil thread inserts for a durable and safe repair. For further details regarding industrial fasteners and matching tools, please contact Macros Fastening Systems for top-of-the-line products.
