Buyer Questions
Frequently asked questions
How does a concrete screw differ from a regular screw?
A concrete screw has a hardened thread profile specifically designed to cut into concrete and base materials, plus a hardened body that won't strip during installation. Regular screws would not survive contact with concrete. The blue ceramic-zinc coating is also corrosion-protective and visually distinctive.
