S-90420A724 Length 2 13/16" Wood Screws

Key Features & Benefits at a Glance

• Efficient self-drilling installation with integrated cutting wings and No. 5 drill point eliminates pre-drilling, saving time and labor in sheet metal and wood applications
• Superior corrosion resistance provided by galvanic barrier coated 18-8 stainless steel construction ensures long-term durability in harsh environments
• Optimized thread engagement with 1-1/2" thread length and thread forming design creates secure, vibration-resistant fastenings
• Clean flush mounting achieved through standard flat head profile with Phillips No. 3 drive for smooth surface finishes
• Enhanced material compatibility with partially threaded design and right-hand threading prevents material splitting in wood and sheet metal
• Precision dimensional control with 2-13/16" length and consistent thread pitch ensures reliable performance in repetitive industrial applications

Professional Applications & Engineering Value

These No. 12 self-drilling screws with cutting wings are engineered to solve critical installation challenges in sheet metal and wood applications. The combination of thread forming technology and specialized No. 5 drill point (45/64" tip length) enables direct penetration without pilot holes, significantly reducing assembly time while preventing material damage. The galvanic barrier coated 18-8 stainless steel construction provides exceptional protection against galvanic corrosion when fastening dissimilar metals, making these Phillips flat head screws ideal for HVAC systems, metal building construction, and outdoor wood structures where environmental exposure is a concern. The partially threaded design with right-hand thread direction ensures optimal clamping force distribution while minimizing the risk of material splitting in delicate wood applications.
