Key Features & Benefits at a Glance
- Self-drilling design with cutting wings eliminates pre-drilling, saving time and labor costs in wood and sheet metal applications
- Zinc plated steel construction provides reliable corrosion resistance for extended service life in demanding environments
- Fully threaded UNC coarse thread profile ensures maximum material engagement and superior holding power
- Optimized drill point technology delivers clean, precise installations without material splitting or damage
- Phillips drive compatibility offers widespread tool accessibility and efficient installation torque transfer
- Versatile material compatibility handles wood thicknesses from 0.75" to 2.75" and metal gauges from 0.11" to 0.375"
- Thread forming tapping method creates strong, secure threads without generating chips or debris
Professional Applications & Engineering Value
These 1/4"-20 self-drilling wood screws with cutting wings are engineered to address common installation challenges in construction and fabrication. The zinc plated steel composition provides essential corrosion protection while maintaining high tensile strength. The integrated drill point and wing design penetrates sheet metal and wood substrates efficiently, eliminating separate drilling operations and reducing assembly time by up to 50%. The UNC coarse threads and thread forming action create permanent, vibration-resistant connections in structural wood framing, metal building components, and composite material assemblies. The fully threaded configuration ensures consistent load distribution along the entire fastener length, preventing joint failure in high-stress applications.
Specification Summary & Compliance
Manufactured to precise dimensional standards with UNC thread form and Class 2A tolerance for consistent performance. Features standard flat head profile with No. 3 Phillips drive for secure installation. Compliant with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances. The thread forming manufacturing process ensures reliable performance in various material densities without requiring pre-tapped holes.
