Professional Applications & Engineering Value

These No. 6 zinc-plated steel wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak grip in engineered woods. The thread forming design displaces wood fibers rather than cutting them, which minimizes stress and enhances pull-out resistance in plywood and OSB applications. The flat head with a 90° countersink angle allows for a smooth, flush surface, ideal for cabinetry, furniture, and drywall where aesthetics matter. Made from durable zinc-plated steel, these screws resist rust and corrosion, extending service life in humid or variable conditions. The dual Phillips/Square drive offers flexibility, reducing tool slippage and speeding up installation for professionals in construction and woodworking sectors.

Specification Summary & Compliance

This product features a thread diameter of 0.138" with approximately 18 threads per inch, ensuring precise fit in accordance with standard inch measurements. The screws are fully threaded with a right-hand direction and pointed tip for efficient driving. Compliance includes adherence to RoHS 3 (2015/863/EU) regulations, confirming they are free from hazardous substances and suitable for environmentally conscious projects. Manufactured to consistent dimensional tolerances, these screws provide reliable performance in various wood-based materials.
