Frequently Asked Questions (FAQs)
1. What's better than a helicoil?
Time Sert inserts for head bolt applications are much thicker than the Helicoil brand. They are more like a solid metal bushing which is threaded on the inside and out. The Time Sert brand insert is installed with a special driver.
2. Can you fix stripped threads?
The complete repair for stripped threads is to use a coil-type thread insert. These inserts will give the bolt hole completely new threads which accept the size of the original bolt. In order to use inserts, you must drill the damaged holes slightly larger so that it can take the thread insert.
3. What is a thread repair kit used for?
A helical insert is screwed into a hole to replace broken threads. Thread repair kids allow damaged threads in a hole to be removed and replaced with new threads of the same size. They may also be used to provide strong threads in soft materials such as aluminum.
