Professional Applications & Engineering Value

These No. 16 wood screws are engineered to address common fastening challenges in woodworking and construction applications. The zinc-plated steel construction provides essential corrosion protection for both indoor and outdoor projects, while the thread forming technology creates superior holding power by displacing wood fibers rather than cutting them, resulting in tighter, more secure connections. The partially threaded design with 0.268" thread diameter and 9 threads per inch ensures maximum grip strength while minimizing the risk of wood splitting. The flat head profile with standard 82° countersink angle allows for flush installation in furniture, cabinetry, decking, and structural wood assemblies. These wood screws deliver consistent performance across various wood densities, from softwoods to hardwoods, making them ideal for professional contractors and woodworking specialists seeking reliable, long-term fastening solutions.

Specification Summary & Compliance

These wood screws feature precise dimensional specifications including a 2-1/2" length, 0.268" thread diameter, and 9 threads per inch with right-hand threading. The manufacturing adheres to standard inch system measurements with proper head diameter (0.544") and head height (0.164") tolerances. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in commercial and residential applications. The thread forming tapping method and pointed tip design facilitate easy installation while maintaining structural integrity in wood substrates.
