Professional Grade Fastening for Masonry IMSCREWS presents our heavy-duty Blue Concrete Screws, engineered for reliability in solid concrete, brick, and block applications. Whether you are anchoring shelves, installing window frames, or securing wood to masonry, these fasteners provide the holding power you need. Key Features: Material: Heat-treated Carbon Steel for maximum hardness. Coating: Blue Ceramic/Epoxy coating provides excellent rust resistance (tested for weather exposure). Thread Type: Hi-Lo thread pattern ensures easy driving and high pull-out resistance. Installation Tip: Always use a hammer drill with a 3/16" carbide-tipped masonry bit. Clean the hole of dust before driving the screw for the best performance.

Key Features

• [HARDENED CARBON STEEL] Manufactured from high-grade carbon steel with a specialized blue epoxy coating. These masonry screws offer superior tensile strength to prevent snapping during installation and provide long-lasting corrosion resistance in harsh environments.
• [SELF-TAPPING HIGH-LOW THREAD] Features an advanced high-low thread design that cuts deeply into masonry materials. The high thread provides a firm mechanical interlock, while the low thread assists in dust removal, ensuring a secure hold in concrete, brick, and hollow blocks.
• [FLUSH FLAT HEAD DESIGN] The flat head profile allows the screw to sit flush with the surface for a clean, professional finish. Ideal for fastening furring strips, electrical boxes, and wood framing to masonry without protruding heads.
• [INSTALLATION REQUIREMENTS] Requires a pre-drilled pilot hole using a standard 3/16-inch masonry drill bit (drill bit not included). Ensure the hole is drilled at least 1/4-inch deeper than the screw penetration depth for optimal grip and safety.
• [SPECIFICATIONS] Package contains 10 pieces of Blue Concrete Screws. Size: 1/4 inch diameter x 2-1/4 inch length. Drive Type: Flat Head. Coating: Blue Rust-Resistant Epoxy. Securely packaged to prevent loss or damage during transit.
