If you’re having trouble securing a screw, a bolt, or even a spark plug, it may be because there is damage to the thread. This is a common problem, particularly in large machines where there is a lot of vibration. It can also be caused by fastening a part too tightly or applying it at the wrong angle, so the thread is incorrectly aligned. If you experience this issue, you should address it immediately to avoid machine breakdown.
The good news is that it is usually a simple fix!
We would recommend using a Thread Repair Kit, commonly known as a ‘Helicoil Kit’. Helicoil kits come in a range of sizes so they can be used for numerous parts and machines to repair damaged threads.
If you purchase a Thread Repair Kit from HTS Spares, you will find the following items in the box:
Before starting, you will need to determine the size of the Helicoil you need for your application. Use the screw or bolt to identify the:
Diameter: Using a Caliper, measure the diameter of the bolt.
Pitch: Using a Pitch Gauge, measure the pitch of the bolt or screw to determine what pitch size is needed. The pitch is the size of each thread on an insert.
Example: If the thread diameter is 10mm and the pitch measures 1.5mm you will need a M10 x 1.5 kit.
