FAQ

Q: What tool is needed to drive these screws?
A: A pin-in-hex (hollow hex) security driver is required. Standard Allen keys will not fit due to the center pin. Keszoox also sells compatible pin-in-hex security driver sets.

Q: Are these screws corrosion-resistant for outdoor use?
A: Yes. A2-70 grade 304 stainless steel provides good corrosion resistance for most outdoor environments. For marine or highly corrosive environments, consider A4-80 grade 316 stainless steel.

Q: What is the security level of pin-in-hex screws?
A: Pin-in-hex is classified as a Level 2 security fastener. It deters casual tampering and requires a specific driver, but is not rated for high-security applications requiring Level 3+ fasteners (e.g., Pentalobe, Tri-Wing).
