- Optimized thread engagement with UNC coarse threading and thread forming design for strong, vibration-resistant connections
- Enhanced installation control through Phillips No. 3 drive system, reducing cam-out and improving torque transfer
- Versatile material compatibility designed for wood (0.75"-2.875") and sheet metal (0.06"-0.31") applications
- Reliable flush mounting with standard flat head profile that sits neatly with material surfaces
- Environmental compliance assurance meeting RoHS 3 standards for safe industrial use
Professional Applications & Engineering Value
Engineered for demanding wood construction and sheet metal fabrication applications, these self-drilling screws eliminate the need for pre-drilling, significantly reducing installation time and labor costs. The corrosion-resistant coated steel construction provides critical protection against environmental factors, while the cutting wings and No. 4 drill point work in tandem to efficiently clear material debris during penetration. The UNC coarse threading ensures rapid installation and superior pull-out resistance in both wood and metal substrates, making these industrial wood screws ideal for structural applications where reliability and speed are paramount.
Specification Summary & Compliance
This 1/4"-20 x 4" wood screw features standard UNC coarse threading with thread forming tapping method, ensuring precise fit and strong fastening performance. The screw maintains dimensional accuracy with a flat head profile (0.485" diameter, 0.185" height) and partially threaded design with minimum thread length of 2 3/16". Manufacturing and material compliance includes RoHS 3 (2015/863/EU) certification, guaranteeing environmental safety standards for industrial applications.
