About this item

Tapcon® 5/16 in. x 2‑3/4 in. Hex Washer Head Concrete Screws – 50 Count

These heavy‑duty 5/16 in. x 2‑3/4 in. Tapcon® Hex Washer Head Concrete Screws are engineered for superior holding power in concrete, brick, and block. Designed to cut their own threads during installation, they deliver strong, vibration‑resistant anchoring without the need for inserts or expansion hardware.

The hex washer head provides enhanced driving stability, reducing the risk of stripping or cam‑out under load. A corrosion‑resistant Blue Climaseal® coating helps protect against rust and environmental wear, making them suitable for both indoor and outdoor applications. This 50‑count box offers excellent value for contractors completing mid‑volume fastening projects that demand strength, consistency, and reliability.

Key Features

  • 5/16‑inch large‑diameter design for maximum holding strength in demanding applications
  • Hex washer head ensures optimal torque transfer and reduced driver slippage
  • Thread‑forming design cuts into concrete, block, and brick for secure, high‑grip anchoring
  • Blue Climaseal® corrosion‑resistant coating enhances durability in harsh environments (consistent with verified Tapcon lines)
  • Requires no inserts, shields, or sleeves, reducing installation time
  • Ideal for heavier fixtures, including brackets, supports, conduit straps, ledger boards, and mechanical mounts
