Product Information

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.
• HEX HEAD 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.
• HEX WASHER HEAD - DRIVE TWO WAYS: Install with a T30 star bit or a 5/16" hex socket/nut driver. The integrated washer flange seats flush and secure against brackets, plates, and furring strips.
• CORROSION-RESISTANT BLACK FINISH: Hardened carbon steel with baked-on blue ruspert coating resists rust and corrosion while blending with the classic blue masonry-fastener look contractors recognize on the jobsite.
• ALL-IN-ONE MASONRY KIT ($16 ADDED VALUE): 100-pack of heavy-duty 1/4" x 6" 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), one T30 star driver bits, and one 5/16" hex head driver bit ($16 retail value). Enjoy consistent, pro-grade quality across the entire box!

Product Description

Glazier Products Black Concrete Screws (1/4" x 6", Hex Head, Star Drive) fasten directly into concrete, brick, block, and mortar with no separate anchor required - drill a 3/16" pilot hole 1/4" deeper than screw length and drive in screw. Hardened carbon steel with a ruspert coated black finish delivers corrosion resistance and holding power while blending with dark fixtures, ironwork, railings, and modern finishes. 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 hex washer head drives with either a star bit or a standard hex socket, and its integrated flange seats firmly against brackets, plates, and lumber. Ideal for contractors, 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.
