Frequently Asked Questions

Q: Can these blue concrete screws be used without a plastic wall anchor?

A: Yes! These self-tapping masonry screws are designed to cut directly into brick, concrete block, and cement — no separate plastic anchor is needed. Simply pre-drill a pilot hole of the appropriate diameter and drive the screw straight in for a secure hold.
