Description
These #10 x 4" Square Drive Flat Head Wood Screws are designed for heavy-duty wood fastening, making them ideal for decking and exterior construction. Manufactured from 18-8 stainless steel, they offer excellent corrosion resistance for long-term outdoor use.
The 82-degree countersunk flat head allows the screw to sit flush with the surface, while the square drive reduces cam-out for better torque control. Featuring a Type 17 point, these screws cut cleanly into wood fibers, minimizing splitting and eliminating the need for pre-drilling in most applications.
Produced to ASME B18.6.1 standards, these screws deliver strength, precision, and clean finishes for demanding wood projects.
