Hillman 41572 Flat Head Tapper Concrete Screw 18 Count

Product Description

The HILLMAN 41572 is a flat head tapper concrete screw designed to anchor objects directly into concrete, brick, and block without anchors or inserts. The hardened high-low thread cuts its own path into masonry as the screw is driven, creating a secure mechanical hold. Installation follows a straightforward two-step process: drill a pilot hole to the specified diameter, then drive the screw. The 41572 measures 1/4 inch in diameter and 1-3/4 inches in length. This pack contains 18 screws. Tappers installed with this method can be removed and re-inserted into the same hole when access or repositioning is needed.

This screw is well suited for light-duty masonry fastening tasks in residential and light commercial settings. Typical applications include window installations, interior handrails, metal door frames, storm shutters, interior lighting fixture mounting, thresholds, and screened enclosures. The flat head profile sits flush against the surface after installation, making it appropriate for finished or visible surfaces. Tradespeople and experienced DIYers working on interior and exterior masonry attachment tasks will find this a practical, reusable fastening solution.

Installation Notes

Installation requires drilling a properly sized pilot hole into the masonry substrate before driving the screw. Use a hammer drill with a carbide-tipped bit sized to match the screw diameter for clean hole formation. Ensure all power to adjacent electrical systems is off before working near wiring or fixtures. Follow applicable local building codes and manufacturer pilot hole depth recommendations when securing structural or life-safety components such as handrails.
