FAQs: Your Carbon Steel Screw Questions Answered

Q: Can carbon steel screws be used outdoors?
A: Yes, but only with galvanized or nickel-plated coatings to prevent rust.

Q: Are carbon steel screws stronger than stainless steel?
A: Yes, but stainless steel resists corrosion better. Choose based on environment.

Q: How do I prevent screws from loosening due to vibration?
A: Pair with nylon lock nuts or apply thread-locking adhesive.

Q: What’s the difference between low and high carbon screws?
A: Low carbon = more flexible, high carbon = harder but brittle.
