S-90420A763 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Self-drilling capability with No. 2 drill point and 19/64" tip length eliminates pre-drilling, saving time and labor in sheet metal and wood applications
• Superior corrosion resistance from galvanic barrier coated 18-8 stainless steel construction ensures long-term durability in harsh environments
• Full threading provides maximum grip and holding power throughout the entire fastener length
• Phillips drive with No. 3 size offers secure installation and reduced cam-out risk during high-torque applications
• Flat undercut head design sits flush with material surfaces for clean, professional finishes
• Thread forming technology creates strong, secure threads in base materials without chip removal
• Right-hand 14 TPI threading ensures compatibility with standard industrial equipment and consistent fastening performance

Professional Applications & Engineering Value

These No. 12 self-drilling screws are engineered to solve critical fastening challenges in sheet metal and wood applications. The combination of 18-8 stainless steel with galvanic barrier coating provides exceptional corrosion resistance, making them ideal for outdoor structures, industrial equipment, and marine environments where moisture exposure is a concern. The self-drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs while preventing material damage from misaligned pilot holes. The flat undercut head design ensures flush mounting without surface protrusions, while the thread forming technology creates stronger, more reliable connections by work-hardening the surrounding material. These Phillips drive fasteners deliver consistent performance in high-volume assembly operations, making them invaluable for manufacturing, construction, and maintenance professionals seeking efficiency and reliability.

Specification Summary & Compliance

These precision-engineered fasteners feature a No. 12 screw size with 1-1/2" length and 0.216" thread diameter. The 14 threads per inch configuration follows standard industrial specifications, while the flat head with undercut profile (0.415" diameter, 0.09" height) ensures proper seating. Manufactured from 18-8 stainless steel with galvanic barrier coating, these self-drilling screws comply with industry standards for thread forming applications and are suitable for use in various industrial environments requiring corrosion-resistant fastening solutions.
