Why do bolts lose their strength?
Over time bolt s and threads sometimes lose their strength. Due to friction or corrosion, the threads can deteriorate. Having these weak threads can prevent you from being able to tighten down a bolt. The first option is looking at the bolt hole.

Can you drill a hole in a bolt?
If most of the threads have been a victim of damage you may be able to increase the size of the hole. As long as there is enough room on the outside you may be able to drill out a larger hole. This will allow you to rethread the hole and give you the ability to use a larger bolt.

What happens if you misalign bolts?
Misalignment: If parts are misaligned during assembly, the bolts may not go straight into the holes, resulting in cross-threading or deformed threads.
What is a thread chaser?
Thread Chaser: A thread chaser rolls and reforms the deformed threads. If possible, chase the threads starting from the undamaged section. This can be done for spark plugs or caliper bolts, for example.
Can you drill and tap a hole?
Drill and Tap: You can drill and tap the hole larger to accommodate a larger fastener. Going up one or two sizes is allowable in many circumstances, but be sure to use the correct drill bit to retain the strength of the attachment.

Nevertheless, a tap and die set is a necessary addition to anyone’s toolbox.
Can you assemble a bolt with stripped threads?
It’s only a matter of time before you run across a stripped bolt-hole or stripped threads in your DIY repair project.

Can you use OEM bolts?
Epoxy: For low-torque applications, high-strength epoxy can allow you to use the OEM bolt size.

Once the epoxy cures, install new bolts as needed.
How to align a tap handle?
