For the economical repair of damaged or worn threads (of all materials) and as a design element for thread reinforcement when using materials with low shear strength (e.g. aluminum, aluminum-magnesium alloys). The use of wear-free HeliCoil thread inserts not only repairs the thread but also increases the thread load-bearing capacity.
Execution:
High-strength, free-running HeliCoil®plus thread inserts made of stainless steel with high wear resistance, low thread friction in tight tolerances, high surface quality as well as corrosion resistance and heat resistance. The flexible design enables even load and stress distribution and thus produces durable screw connections of the highest quality for all operating loads (static, dynamic) with ideal force transmission. Uncomplicated, quick assembly, creates an internal thread that is true to gauge and can be used on both sides.
Complete repair kit for M4 thread sizes in a plastic case.
Application:
1. Drill out the defective thread with the enclosed drill.
2. Check the tap and threaded bolt.
3. Cut the holding thread with the special HeliCoil tap.
4. Turn the thread insert into the holding thread using the installation tool.
5. Remove the tang with the tang breaker
