Overview

Minerallac Company 10 x 2-1/2" Flat Head Square Drive Wood Screws (SKU: 13040J) are precision-engineered zinc-plated fasteners designed for wood-to-wood connections in construction, carpentry, and general woodworking. These screws feature a flat head for flush installation and a square drive for superior torque transfer, reducing cam-out and ensuring reliable engagement with #2 square drive bits. The zinc plating provides corrosion resistance, making them suitable for both indoor and outdoor applications where durability is required. Key specifications include a #10 gauge size with a 2-1/2" length, optimized for securing wood framing, decking, cabinetry, and structural connections. Each jar contains 100 screws, with master cartons holding 600 screws for bulk purchasing. The square drive design minimizes driver bit slippage, improving installation efficiency and reducing rework in high-volume applications. These screws are ideal for general construction projects, furniture assembly, and repair work where a clean, recessed finish is necessary. The zinc finish resists rust and corrosion, extending service life in exposed or humid environments. Unlike Phillips or slotted drives, the square drive ensures consistent torque application without cam-out, which is critical in repetitive fastening tasks. The combination of size, drive type, and corrosion-resistant coating makes them a versatile choice for woodworking applications requiring strength, precision, and longevity.
