Thread Repair Kits for oil drain screw threads M18 x 1,5, 10B, HexTap LS HexTap LSN, 9

• For restoring defective internal threads in components when you want to use screw connections safely again.
• For service work, maintenance and assembly when thread stripping or damaged flanks need to be avoided.
• Process: manual or assisted drive depending on your tool holder and machine configuration.
• Use: thread cutting, thread re-cutting and thread cleaning depending on the condition of the thread.
• Suitable when you aim for repeatable thread quality in series production or repair processes.

Note Clean preparation reduces breakouts and jamming. Remove residues and check the result before assembly.

• Makes service and assembly easier because screw connections engage reproducibly again.
• Practical repair process for maintenance and workshop use.
• Helps reduce downtime because the component can often remain in use.
• Ensures defined thread geometry in the repaired area when the process is carried out cleanly.

• Not suitable if the base material is heavily cracked or if the repair area does not allow sufficient wall thickness by design.
• For high-performance applications, you need consistent process control, a clean bore and suitable tools; otherwise, repeatability decreases.

1. Check the damaged internal thread and decide whether a repair is structurally reasonable.
2. Align the component securely and ensure clean chip removal and lubrication at the machining point.
3. Create the receiving thread with the appropriate tool and keep the engagement consistent.
4. Clean the bore and remove residues so that the insert sits correctly.
5. Insert the wire thread insert carefully with the installation tool until the position is correct.
6. Check the fit and make sure the screw runs freely and the thread does not jam.
7. Remove the tang according to the system specification and clean the area afterwards.

What does the thread designation M stand for?
M indicates a metric ISO thread. It is the common system in mechanical engineering and metal construction and is widely used in assembly.

Why is the tool material important?
The material influences tool life and process reliability. For tough or alloyed materials, you often need a version designed for this purpose and stable guidance.

Do you need lubrication when cutting threads?
In most cases, suitable lubrication helps reduce friction and heat. This improves the surface finish and lowers the risk of jamming or breakouts.

How do you avoid tilting when starting?
Make sure the tool is aligned with the axis and guided stably. If the tool starts at an angle, flank errors occur and the run becomes uneven.

How do you check the result after machining?
Check the run with the appropriate screw or a test element and look for even resistance. For critical connections, also check the fit and assembly function.

When is thread repair worthwhile instead of replacing the part?
If the component is structurally intact and only the internal thread is damaged, a repair can restore assembly. In the case of cracks or severe material loss, another repair method is often more suitable.
