• Professional flush finish with standard oval head profile and 82° countersink angle for seamless integration into wood surfaces
• Optimized wood penetration with pointed tip and partial threading design that reduces splitting while maximizing grip strength
• Reliable drive engagement featuring No. 2 Phillips drive for secure tool connection and reduced cam-out during installation
• Material-specific compatibility with pre-drilled hole sizes for both hardwood (3/32") and softwood (5/64") applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 8 brass oval head wood screws deliver exceptional engineering value through their specialized thread forming technology and partial threading design. The brass material provides inherent corrosion resistance, making them ideal for applications where moisture exposure or aesthetic appeal are concerns. The thread forming tapping method creates stronger, more permanent connections in wood by compressing material rather than removing it, significantly reducing the risk of loosening over time. With their standard oval head profile and 82° countersink angle, these Phillips drive screws sit flush with wood surfaces, eliminating protrusions while maintaining structural integrity. The pointed tip and optimized thread pitch ensure smooth penetration in both hardwood and softwood applications, while the right-hand threading follows industry standards for straightforward installation. These features collectively address common wood fastening challenges including material splitting, corrosion degradation, and installation efficiency.

Specification Summary & Compliance

These wood screws feature a No. 8 screw size with 0.164" thread diameter and 15 threads per inch in a right-hand threading configuration. The partial threading extends for a minimum of 1" on the 1-1/2" length, with standard Class 2A thread tolerances ensuring consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming they're free from restricted hazardous substances. The oval head design with 0.332" head diameter and standard profile ensures proper seating in pre-drilled holes sized at 3/32" for hardwood and 5/64" for softwood applications.
