FAQ:

Q: What is the difference between pan head and countersunk head self-tapping screws?
A: The pan head stays exposed and delivers stronger clamping pressure; the countersunk head sits flush for a smooth surface finish.

Q：Can this screw be used on hard solid wood?
A：Yes, pre-drilling a pilot hole is recommended for extra hard wood to avoid cracking.

Q: Can stainless steel pan head self-tapping screws be used on plastic parts?
A: Yes. Please control the tightening torque, as excessive force may crack plastic substrates.

Q: Can custom lengths and packaging be arranged?
A: Yes, non-standard lengths, neutral packages and private label packing are acceptable.
