This guide will dive straight into the essential components of a Helicoil thread repair kit and provide a step-by-step guide on how to use it effectively.
What are the Components of a Helicoil Thread Repair Kit?
A typical Helicoil thread repair kit should include the following critical tools. Each tool has its own role in helping to achieve a successful thread repair. This guide will use a professional Helicoil thread repair kit from Orion Motor Tech as an excellent example.
- Breaking Pin Tool: This tool is used to break off the tang of the insert once it is installed. The tang is a small piece of wire at the end of the insert that helps guide it during installation.
- Screw Tap: The tap is used to cut new threads in the drilled hole. This prepares the hole to accept the Helicoil insert.
- Drill Bit: The drill bit is specifically sized to prepare the hole for tapping. Drilling ensures the hole is the correct diameter for the new threads.
- Installation Tool: This tool is used to screw the Helicoil insert into the newly tapped hole. It ensures that the insert goes in smoothly and to the correct depth.
- Wire Thread Inserts: These are the heart of the thread repair kit. The inserts are usually made of quality steel to form new and durable threads in the repaired hole.
- Thread Insert Box: This box is designed to keep all thread inserts organized and easily accessible, ensuring that you have everything you need at your fingertips.
