1/4" x 5" Concrete Screws, White Flat Head Countersunk Star Drive, 100 Pack w/ 2 Drill Bits & 2 Star Driver Bits Included - Heavy Duty Masonry Anchor Screws for Concrete, Brick, Block - Carbon Steel
- 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 WHITE FINISH: Hardened carbon steel with baked-on white ruspert coating resists rust and corrosion while blending with painted surfaces, siding, trim, and light masonry.
- 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!

Hardened carbon steel with a ruspert coated white finish delivers corrosion resistance and holding power while blending with painted surfaces, siding, trim, and light masonry. The partially threaded design (1.97" of 1/4"-12 UNC thread) lets the screw clamp material tight to the masonry while the threads anchor in the base. The T30 star drive recess resists cam-out under high torque, so screws drive faster with fewer stripped heads. The countersunk flat head finishes flush with the work surface for clean, professional results on wood-to-masonry connections. Ideal for contractors, glaziers, glaziers, remodelers, and DIYers fastening sill plates, ledgers, furring strips, electrical boxes, brackets, and fixtures to concrete and masonry. Sold in a jobsite-ready 100 pack.
