S-90415A350 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated self-drilling tip that penetrates up to 0.098" thickness in steel and sheet metal
• Superior corrosion resistance through 18-8 stainless steel construction with protective coating for extended service life in harsh environments
• Enhanced driving efficiency with Phillips No. 2 drive design that provides secure tool engagement and reduces cam-out
• Optimal material displacement through thread forming (BSD) technology that creates stronger, more secure fastening points
• Maximum holding power achieved through fully threaded design that distributes clamping force evenly across the entire fastener length
• Streamlined installation with rounded pan head profile that sits flush against surfaces while allowing for higher torque application
• Regulatory compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing applications

Professional Applications & Engineering Value

These No. 8-18 tapping screws deliver exceptional value in industrial fastening applications where steel, stainless steel, and sheet metal assemblies require reliable, permanent connections. The corrosion-resistant coated 18-8 stainless steel construction ensures long-term performance in demanding environments, while the self-drilling tip eliminates the time and cost associated with pre-drilling operations. The thread forming design creates precise mating threads in parent material without generating chips, resulting in superior pull-out resistance and vibration resistance. The combination of Phillips drive and fully threaded configuration provides consistent clamping force distribution, making these BSD tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and structural metal framing where drilling efficiency and joint integrity are critical.

Specification Summary & Compliance

This No. 8-18 x 3/4" tapping screw features precision right-hand threads with 18 threads per inch and 0.164" thread diameter, manufactured to industry standards for thread forming applications. The fastener maintains dimensional accuracy with standard inch measurements and includes a No. 2 drill tip capable of penetrating 0.098" maximum thickness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial and manufacturing applications.
