S-90106A114 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated drilling tip that penetrates up to 0.098" thickness in steel and sheet metal, reducing installation time and labor costs.
• Superior corrosion resistance provided by 410 stainless steel material, ensuring long-term reliability in demanding industrial environments.
• High-torque driving capability with external hex head design, allowing for secure fastening and reduced risk of tool slippage during installation.
• Enhanced grip and load distribution from the flanged design, which helps prevent loosening under vibration and provides a larger bearing surface.
• Consistent thread engagement through fully threaded, thread-forming (BSD) design that creates strong, wear-resistant threads in base materials.
• Wide material compatibility for use in steel, stainless steel, and sheet metal applications, offering versatile fastening solutions.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting strict environmental and safety requirements for industrial components.

Professional Applications & Engineering Value

These No. 8 self-drilling tapping screws are engineered to address common industrial fastening challenges by combining 410 stainless steel durability with a thread-forming BSD design. The integrated drilling tip eliminates the need for separate drilling operations, significantly speeding up assembly in steel, stainless steel, and sheet metal applications while reducing equipment costs. The fully threaded construction and flanged hex head ensure uniform stress distribution and high clamp load, preventing joint failure in high-vibration environments. This makes them ideal for HVAC systems, metal framing, and machinery assembly where corrosion resistance and installation efficiency are critical.

Specification Summary & Compliance

This No. 8 x 1-1/2" self-drilling screw features a 0.164" thread diameter with 18 TPI right-hand threads and complies with BSD thread-forming standards. The hex head (1/4" width) and flanged design (0.348" diameter) provide secure driving and seating. Manufacturing and material specifications adhere to industrial fastening requirements, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
