1/4" x 6" Concrete Screws, Black Flat Head Countersunk Star Drive, 100 Pack w/ 2 Drill Bits, 1 Star Driver Bit & 1 Hex Driver Bit Included - Heavy Duty Masonry Anchor Screws for Concrete, Brick, Block Black 1/4" x 6"

Specifications:

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.
