Full details
This 3-piece Lang Tools Thread Restorer File Set is ideal for mechanics, technicians, and DIY enthusiasts who need to quickly repair damaged external threads on bolts, studs, and shafts. Its primary benefit is its versatility, offering a wide range of SAE and metric thread pitches to cover most common applications, saving time and preventing the need for replacement parts. A potential caveat is that extensive damage may require professional welding and re-machining rather than simple thread restoration.

FAQs
What types of threads can this set restore?
This set restores external threads on bolts, studs, and shafts. It includes a wide range of SAE and metric thread pitches for common applications.
How do I know which file to use?
You need to determine the thread pitch of the damaged fastener. For SAE, this is measured in threads per inch (TPI). For metric, it's millimeters per thread. Match this measurement to the markings on the files in the set.
Can this set repair stripped threads?
This set is designed for re-threading damaged or slightly burred threads. It may not be effective for completely stripped or heavily damaged threads that require professional repair.
What are the dimensions of the files?
The product dimensions for the set, including packaging, are 210mm (Width) x 10mm (Height) x 45mm (Depth).
Is this set suitable for internal threads?
No, this thread restorer file set is designed specifically for external threads only.
How should I maintain the files?
After use, clean the files to remove metal filings and debris. Store them in the provided pouch to protect the cutting edges and prevent rust.
What is the weight of the set?
The weight of the set is approximately 499g.
Troubleshooting
File not cutting threads effectively
Ensure you are using the correct file for the thread pitch. Check if the threads are too severely damaged for simple filing. Make sure you are using a consistent back-and-forth or diagonal motion.
Difficulty selecting the correct thread pitch
Visually compare the damaged thread to the pitch markings on the file. If unsure, use a thread gauge or a known good fastener of the same size to determine the pitch.
File seems to be making threads worse
Verify that you are using the correct file pitch and applying consistent pressure. Overly aggressive filing or using the wrong file can exacerbate damage. Ensure the file is clean and free of debris.
