S-90106A543 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient self-drilling capability with a No. 3 drill tip that eliminates pre-drilling, saving time and labor costs on steel, stainless steel, and sheet metal up to 0.21" thick.
• Enhanced holding power through thread forming (BSD type) design, which creates strong, secure threads without generating chips.
• Integrated flange design provides a larger bearing surface for improved load distribution and vibration resistance, reducing the need for separate washers.
• Easy installation and high torque application with an external hex head, allowing for quick, secure driving using standard tools.
• Full threading ensures consistent grip along the entire 3/4" length, offering versatile fastening in various material thicknesses.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe, sustainable use in global industrial supply chains.

Professional Applications & Engineering Value

This 1/4"-14 TPI flanged tapping screw is engineered to address common challenges in metal fabrication and assembly, such as the need for speed and reliability. The 410 Stainless Steel material offers excellent strength and corrosion resistance, making it suitable for outdoor or corrosive environments. Its self-drilling No. 3 tip penetrates up to 0.21" in steel, stainless steel, and sheet metal, streamlining workflows by eliminating separate drilling steps. The thread forming (BSD) design ensures tight, durable threads that resist loosening under vibration, while the flanged hex head provides secure seating and distributes clamp load effectively. Ideal for HVAC, automotive, and construction applications, this screw reduces installation time and enhances structural integrity in demanding industrial settings.
