How to repair a hole in a bolt?

How to tell if a bolt hole is damaged?
Symptoms of a badly damaged bolt-hole range from a bolt that loses grip when applying moderate torque, to one that spins freely. The repair methods also vary greatly. When used appropriately, a simple chemical thread-filler works remarkably well. The popular thread-insert repair method returns a hole to its original size. Sometimes using a longer nut and bolt solves the thru-hole issues that cause inserts problems, such as insert pass through.
What is thread repair insert?
A thread-repair insert acts as a bushing between an over-sized hole and a properly sized bolt. A popular insert has an expanding coil design; others look like a standard bushing.

Why does a blind hole stop before it passes through a block?
A blind hole stops before it passes through the block. Debris packed into the bottom of a blind hole can make a bolt bottom-out prematurely. This common error initially leads to loose fitting parts and leaking gaskets. Trying to tighten a bolt in a debris packed blind hole often leads to stripped threads. Because a thru-hole, sometimes called a clearance hole, passes completely through the block, debris cannot build up.
How to stop a bolt from vibrating?
Use thread-locking material on bolts susceptible to vibration. After the thread-locking material dries, a semi-permanent bond forms, preventing the bolt from vibrating loose. When working with a blind hole application, apply the thread-locking material to the bolt's male threads. Excess thread-locker in a blind hole can stop the end of the bolt from bottoming out. In thru-hole applications, cover the hole's female threads before inserting the bolt.
How to tighten a bolt?
Press the bolt into the hole and twist clockwise. The bolt should turn easily. Once hand-tight, place the proper sized wrench or socket on the bolt's head and tighten as needed.

What is thread locking?
Thread locking material is used on a stripped bolt hole which is made bigger through a thread tap. Hence, the original bolt won’t fit perfectly inside.

What is a helicoil thread?
