Frequently Asked Questions
- Q: Is the black oxide finish rust-proof?
- A: Black oxide provides light corrosion resistance suitable for dry indoor environments. It is not suitable for outdoor, marine, or high-humidity applications. For those environments, choose 304 or 316 stainless steel variants.
- Q: What is the difference between a cap head and a pan head screw?
- A: A cap head (socket head cap screw) has a taller, cylindrical head with a hex socket drive, providing higher torque capacity and a more industrial appearance. A pan head has a lower, rounded profile with a larger bearing surface.
- Q: Can I use these in metal?
- A: These are designed for wood, MDF, and plastic. For thin sheet metal (up to 1.5mm), they can self-tap, but for thicker metal, use machine screws with a pre-tapped hole.
