Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various environments.
• Enhanced holding power through 16 TPI thread forming design, providing a secure, vibration-resistant grip in wood materials.
• Flush, professional finish with an 82° countersink angle and flat head, allowing for seamless integration without protrusions.
• Reliable installation using a Phillips No. 2 drive, reducing cam-out and ensuring efficient, controlled fastening.
• Versatile material compatibility with pre-drilled recommendations for both hardwood (3/32") and softwood (1/16"), minimizing splitting.
• Optimized thread engagement with partial threading and pointed tip, enabling easier starting and reduced driving torque.
• Environmental and regulatory safety by complying with RoHS 3 and REACH standards, supporting sustainable procurement practices.

Professional Applications & Engineering Value

These No. 7 wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak fastening. The zinc-plated steel material offers excellent durability against moisture, while the thread forming design with 16 TPI creates tight, permanent threads in wood without pre-tapping, enhancing pull-out resistance. The Phillips flat head and 82° countersink ensure a smooth, flush surface, ideal for furniture, cabinetry, and framing applications where aesthetics and structural integrity are critical. By specifying pre-drill sizes for hardwood and softwood, these screws reduce installation errors and improve efficiency in professional settings.
