    Self Tapping Flat Countersunk Head Concrete Fixing Screws , Small Steel Blue Concrete Anchors

    Self Tapping Flat Countersunk Head Concrete Fixing Screws , Small Steel Blue Concrete Anchors

    1. Descriptions:


    Concrete screws are hardened screws with a double lead—consisting of alternating raised and lowered threads with notches cut into the raised threads—and a diamond-shape, nail-type point. Special carbide bits are recommended for drilling pilot holes prior to driving concrete screws into masonry.


    The design of the concrete masonry screw anchors allows for anchoring into concrete, brick and block. This product is a self-tapping screw that taps threads into a predrilled hole in masonry materials. The patented Advanced Threadform Technolog lowers installation torque to reduce head snapping, provide higher holding power and deliver the unparalleled performance that professionals expect. The concrete masonry screw anchors are uniquely engineered to provide easy installation and consistently high holding values in most masonry materials. Installation near the edge of concrete is possible because the concrete screw anchors do not create an outward pressure from expansion.

    • Wooden beams
    • Plywood
    • Exterior installation
    • Metal flashing
    • Thresholds
    • and many more

    5. what environment will the concrete screws be installed:


    For indoor dry applications where there is no moisture present. the standard blue Climaseal coated should be sufficient.

    • For wet, moist applications, the 410 stainless steel should be considered. 410 stainless steel concrete screw provide the best rust resistant material for self-tapping masonry screws. The screw is not made from higher quality, more rust resistant stainless steel because the threads would be unable to harden to the correct hardness to tap masonry.
