About this item

375304 — 3/16" x 3‑1/4" Tapcon‑Style Flat Head Concrete Screw – 100 Count

The 3/16" x 3‑1/4" Tapcon‑style Flat Head Concrete Screw is built for strong, dependable anchoring into concrete, brick, and block. With its extended 3‑1/4" length, this screw provides deeper embedment and increased holding strength—ideal for heavier fixtures, thicker materials, and structural applications where standard‑length screws may not be sufficient.

Its flat countersinking head allows for a flush finish, making these screws excellent for wood‑to‑masonry fastening, securing hardware, installing framing, or mounting components that require a clean, professional look. Durable hardened steel construction and aggressive threaded design help ensure smooth driving, reliable grip, and long‑term performance.

Packaged in a 100‑count box, these fasteners are a great choice for contractors, builders, and DIYers who need consistent, high‑quality concrete screws for larger projects.
