Frequently Asked Questions
What are the advantages of coarse threads over fine threads?
- Coarse threads are more durable and have greater resistance to cross-threading and stripping.
- The height of each coarse thread is greater than the corresponding fine thread. So more material is there in between each thread, thus increasing the flank engagement.
How to remove tough binding screws?
- Use an impact wrench with a posi-drive bit.
- Heat the screw head with a soldering iron by holding the tip on the screw head for at least 30 seconds. Apply a fair amount of pressure while trying to twist or loosen the screw.
