Key Features & Benefits at a Glance
- Superior corrosion resistance with durable brass construction for long-lasting performance in humid or outdoor wood applications
- Enhanced driving efficiency with Phillips No. 1 drive that reduces cam-out and provides secure installation
- Maximum holding power through thread-forming technology that creates strong, permanent threads in wood materials
- Reduced splitting risk with partially threaded design that minimizes stress concentration in wood fibers
- Precision installation guidance with specific drill bit recommendations for both hardwood (1/16") and softwood (3/64") applications
- Streamlined workflow compatibility with standard rounded head profile that sits flush for professional finishes
- Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use
Professional Applications & Engineering Value
These No. 4 brass wood screws are engineered to address common challenges in woodworking and carpentry applications. The thread-forming tapping method creates precise mating threads in wood substrates without pre-tapping, eliminating the need for additional processing steps while providing exceptional pull-out resistance. The 0.112" thread diameter with 22 threads per inch delivers optimal bite in both softwoods and hardwoods, while the partially threaded design ensures superior clamping force without compromising wood integrity. The brass material offers excellent corrosion resistance for outdoor furniture, marine applications, and high-moisture environments where steel fasteners would deteriorate. With specific drill bit sizing for different wood densities, these Phillips drive screws prevent material damage while maintaining installation efficiency in production environments.
Specification Summary & Compliance
These wood screws feature a No. 4 screw size with 1/2" length and 0.112" thread diameter with approximately 22 threads per inch. The partially threaded design provides 0.333" minimum thread length with right-hand threading direction. Manufactured to inch system standards with precise dimensional tolerances, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial safety and sustainability requirements.
