• Clean, flush installation with standard flat head profile and 82° countersink angle for professional finishes
• Efficient driving performance with No. 2 Phillips drive that reduces cam-out and improves installation speed
• Optimized for different wood types with specific drill bit recommendations (1/8" for hardwood, 7/64" for softwood)
• Reliable partial threading providing maximum holding strength while preventing wood splitting
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated use

Professional Applications & Engineering Value

These Black-Oxide Steel wood screws are engineered to address common challenges in wood joining applications. The thread forming technology creates precise mating threads without removing material, resulting in superior pull-out resistance and vibration resistance compared to conventional wood screws. The No. 12 x 3" size with partial threading provides optimal strength-to-length ratio for medium to heavy-duty wood construction, while the pointed tip ensures easy starting without pilot holes in many applications. The Phillips flat head design with 82° countersink angle allows for flush mounting in furniture, cabinetry, and structural wood assemblies, eliminating protrusions that could snag or create safety hazards. These screws are particularly valuable in woodworking and construction projects where reliable, long-lasting fastening solutions are critical.

Specification Summary & Compliance

These wood screws feature a 0.216" thread diameter with 11 threads per inch and 2" minimum thread length for consistent engagement. The flat head design includes a standard profile with 0.438" head diameter and 0.132" head height. Manufactured to precise dimensional standards with right-hand threading and partially threaded configuration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in commercial and residential applications.
