Special Features

  • NO ANCHORS NEEDED - DRIVES DIRECTLY INTO CONCRETE: Self-tapping 1/4"-12 threads bite into pre-drilled 3/16" pilot holes in concrete, brick, block, and mortar - no plugs, sleeves, or hammer-set anchors required. Just drill, drive, and 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.
  • CONTRACTOR-GRADE 100 PACK PLUS 2 PREMIUM CARBIDE DRILL BITS & 2 STAR T30 DRIVER BITS: 1/4" x 6" partially threaded screws (1.97" thread length) reach through material into solid masonry - sill plates, ledgers, furring strips, brackets, and fixtures. Consistent quality across the box for production work.

Description

Glazier Products Black Concrete Screws (1/4" x 6", Flat 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 countersunk flat head finishes flush with the work surface for clean, professional results on wood-to-masonry connections. 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.
