Professional Applications & Engineering Value

These No. 12 wood screws with black-oxide steel construction and thread forming technology address critical challenges in wood assembly applications. The thread forming design eliminates the need for pre-tapped holes while creating stronger, more vibration-resistant connections that won't loosen over time. The square drive system prevents tool slippage and stripping, ensuring consistent installation depth and reducing rework. With the 82° countersink angle and flat head profile, these screws sit perfectly flush in wood surfaces, eliminating protrusions that could snag or create safety hazards. The partially threaded design allows for superior clamping force, making these fasteners ideal for furniture manufacturing, cabinetry, deck building, and structural wood framing where joint integrity is paramount.

Specification Summary & Compliance

These inch-system wood screws feature a No. 12 screw size with 2-1/2" length and Class 2A thread tolerances. The thread forming tapping method creates 0.216" diameter threads with approximately 11 threads per inch and right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet industrial safety standards for hazardous substance restrictions. The flat head design with standard profile and pointed tip facilitates easy starting and proper seating in wood materials.
