- Exceptional holding power from thread forming technology that displaces material rather than removing it
- Optimized wood penetration with pointed tip and partial threading for reduced splitting in hardwood and softwood
- Precision drill compatibility with recommended 1/16" (hardwood) and 3/64" (softwood) bit sizes for perfect fit
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use
Professional Applications & Engineering Value
These No. 4 wood screws with thread forming technology provide exceptional engineering value for wood assembly applications. The zinc-plated steel construction offers reliable corrosion protection in demanding environments, while the Phillips flat head design ensures flush mounting for aesthetic finishes. The thread forming method creates stronger, more secure fastenings by compressing wood fibers rather than cutting them, significantly reducing the risk of stripping and improving pull-out resistance. With precise 22 threads per inch and 0.112" thread diameter, these screws deliver consistent performance in both hardwood and softwood applications, making them ideal for furniture manufacturing, cabinetry, and construction projects requiring durable, long-lasting wood connections.
Specification Summary & Compliance
This No. 4 x 3/8" wood screw features inch system measurements with precise dimensional tolerances, including 0.195" head diameter and 1/4" minimum thread length. The screw conforms to standard flat head profile specifications with 82° countersink angle compatibility. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial applications.
