Professional Applications & Engineering Value

These No. 12 3-1/2" wood screws with 316 stainless steel composition deliver exceptional performance in demanding wood and plastic-wood composite applications. The thread cutting technology eliminates the need for pre-tapping in dense materials, reducing installation time while preventing material splitting. The square drive flat head configuration ensures maximum torque application without slippage, crucial for production environments where efficiency matters. With partial threading and precise 11 threads per inch configuration, these fasteners provide superior pull-out resistance in decking, furniture manufacturing, and structural wood assemblies. The corrosion-resistant properties of 316 stainless steel make these screws ideal for marine environments, outdoor structures, and applications exposed to moisture or chemicals.
