About this item DIRECT-TO-CONCRETE INSTALLATION (NO ANCHORS NEEDED) Forget the hassle of plugs, sleeves, or hammer-set anchors. These fasteners are engineered to drive directly into masonry materials. Step 1: Drill. Use the premium carbide drill bit to create a 3/16" pilot hole in your concrete, brick, block, or mortar. Ensure the hole is a minimum of 1/4" deeper than the screw's total penetration length. Step 2: Drive. Fasten the screw directly into the hole. The 1/4"-12 threads will naturally bite into the material for a secure hold. Step 3: Done. STAR DRIVE ELIMINATES CAM-OUT: T30 star recess locks the driver bit in place for high-torque installation without stripping - faster installs and fewer damaged heads than Phillips drives, even with impact drivers. FLAT HEAD SITS FLUSH: Countersunk flat head finishes flush with the work surface for a clean, snag-free result - ideal for plywood, furring strips, sill plates, and trim fastened over masonry. CORROSION-RESISTANT BLACK FINISH: Hardened carbon steel with baked-on black ruspert coating resists rust and corrosion while blending with dark fixtures, ironwork, railings, and modern finishes. ALL-IN-ONE MASONRY KIT ($16 ADDED VALUE): 100-pack of heavy-duty 1/4" x 5" screws (1.97" thread length) for anchoring sill plates, ledgers, and brackets into solid masonry. We’ve bundled this with everything you need to get started—two premium 3/16" SDS hammer carbide drill bits (with a 4-1/2" drilling embedment), two T30 star driver bits, and a 5/16" hex head driver bit ($16 retail value). Enjoy consistent, pro-grade quality across the entire box!
