Stripped bolt hole threads are an irritating and frustrating problem that can plague any DIYer. In many cases, the only solution is to replace the entire bolt, but that’s not always the most cost-effective solution. If you’re able to repair the threads, you’ll save time and money by avoiding a replacement.
What Causes Stripped Bolt Hole Threads?
Stripped bolt hole threads can happen for a variety of reasons. The most common cause is over-tightening the bolt, which can cause the threads to become worn and damaged. Other causes can include corrosion, dirt, and other debris that can get trapped in the threads.
Tools Needed to Repair Stripped Bolt Hole Threads
The first step in repairing stripped bolt hole threads is to gather the right tools. You’ll need a tap and die set to repair the threads, as well as a lubricant like WD-40 or a similar product. You’ll also need a wrench or socket set to remove the damaged bolt.
Steps to Repair Stripped Bolt Hole Threads
Step 1: Remove the Damaged Bolt
Using a wrench or socket set, remove the damaged bolt from the hole. It’s important to be careful when doing this, as the damaged threads may be fragile and prone to breaking.
Step 2: Clean the Hole
Using a wire brush, clean the hole of any dirt, corrosion, or debris. This will help ensure a smooth surface for the new threads.
Step 3: Apply Lubricant
Using a lubricant like WD-40, lubricate the hole. This will help the tap glide through the hole more easily.
Step 4: Insert the Tap
Using the tap from the tap and die set, carefully insert it into the hole. Turn the tap clockwise until the threads are cut. Make sure to turn the tap slowly and evenly, or you may damage the threads.
Step 5: Insert the Die
Once the tap has been inserted, insert the die into the hole. Turn the die counterclockwise until the threads are cut. Again, make sure to turn the die slowly and evenly.
Step 6: Re-insert the Bolt
Once the threads have been cut, re-insert the bolt into the hole. Using a wrench or socket set, carefully tighten the bolt. Make sure not to over-tighten the bolt, as this can cause the threads to become damaged again.
