Thread File for Thread Repair
Which size or type do you need?
A thread file repairs damaged threads. You use it for internal and external threads. Pay attention to the pitch. It must match the thread you are repairing. Choose metric, SAE or Whitworth. Check the range of the file. That way you know it fits your thread.
What goes wrong when ordering?
Many mechanics order a file without checking the pitch. That results in a file that does not fit. Measure the pitch of the damaged thread. Use a thread gauge or a caliper. Compare that size with the range on the packaging. This prevents a wrong purchase. A file for fine threads does not work on coarse threads.
Which standard matters?
The file must comply with the standard for thread files. That standard ensures the teeth are sharp and hard enough. Use the file only on damaged threads. Not on new or undamaged threads. This keeps the file sharp for a long time. A thread file is a precision tool. Handle it with care.
This file belongs with threading tools. If the thread is too damaged to dress, look at thread repair tools. Cutting new thread is done with taps or threading dies, and a firm grip comes from tool holders.
