About this item

375312 — 1/4" x 3‑3/4" Tapcon‑Style Flat Head Concrete Screw – 100 Count

The 1/4" x 3‑3/4" Tapcon‑style Flat Head Concrete Screw is engineered for strong, deep‑reach anchoring into concrete, brick, and block. Its extended 3‑3/4" length provides greater embedment and enhanced holding strength, making it ideal for heavier‑duty applications or installations requiring penetration through thicker materials.

The flat countersinking head ensures a flush, low‑profile finish, perfect for wood‑to‑masonry fastening, securing fixtures, mounting hardware, or attaching structural components where a clean appearance and strong grip are essential. Made from hardened steel and designed with sharp, high‑cut threads, this screw delivers consistent performance and reliable drive into dense masonry surfaces.

Packaged in a 100‑count contractor box, these screws offer durability, convenience, and consistent quality for professional construction, renovation, and maintenance tasks.
