Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to high-quality brass construction, ensuring long-lasting performance in humid or outdoor wood applications
- Efficient thread-forming design creates strong, permanent threads in wood without pre-tapping, reducing installation time and improving pull-out resistance
- Optimized for both hardwood and softwood with specific drill bit recommendations (1/16" for hardwood, 3/64" for softwood) to prevent splitting and ensure perfect fit
- Secure Phillips No. 1 drive provides excellent torque transfer and reduces cam-out during installation for consistent seating
- Rounded head profile offers a finished appearance while preventing surface damage and allowing for flush mounting in wood surfaces
- Partially threaded shank allows for stronger clamping force as unthreaded portion pulls materials tightly together
- Full regulatory compliance with RoHS 3 and REACH standards, making them suitable for commercial projects with environmental requirements
Professional Applications & Engineering Value
These No. 4 brass wood screws are engineered specifically for woodworking applications where corrosion resistance and aesthetic appeal are paramount. The thread forming design eliminates the need for separate tapping operations, creating stronger threads that won't strip under stress. The 0.112" thread diameter with 22 TPI provides excellent holding power in both hardwood and softwood materials, while the rounded head style ensures a professional finish without sharp edges. The 5/8" length and partial threading make these Phillips drive screws ideal for joinery, furniture assembly, cabinetry, and decorative wood projects where reliability and appearance matter equally.
Specification Summary & Compliance
These screws feature a 0.112" thread diameter with approximately 22 threads per inch and minimum thread length of 0.417". The partially threaded design with right-hand direction follows standard wood screw specifications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they're free from hazardous substances and suitable for commercial woodworking projects with environmental compliance requirements.
