S-97899A950 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel material for long-lasting performance in harsh industrial environments
• Efficient installation through self-drilling No. 3 tip that eliminates pre-drilling requirements, saving labor time and costs
• Enhanced thread retention with thread forming design that creates stronger, more reliable threads in steel and sheet metal applications
• Maximum torque transmission via external hex head design that prevents tool slippage during installation
• Improved load distribution with integrated flange that provides wider bearing surface and reduces material stress
• Reliable identification through white painted head finish that enables easy visual inspection and quality control
• Full thread engagement along the entire 1½" length ensures maximum holding power in various material thicknesses

Professional Applications & Engineering Value

These thread forming tapping screws are engineered to solve critical challenges in metal fabrication and assembly operations. The 410 stainless steel construction provides excellent strength and corrosion resistance, making them ideal for demanding applications in construction, HVAC systems, and industrial equipment manufacturing. The combination of thread forming technology and drilling tip eliminates the need for separate drilling and tapping operations, significantly reducing installation time and labor costs. The fully threaded design ensures consistent engagement throughout the material thickness, while the flanged hex head provides superior clamping force without requiring separate washers. These BSD tapping screws are particularly valuable in sheet metal and steel applications where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These 1/4"-14 thread forming tapping screws feature precision right-hand threads with standard inch measurements, including 3/8" hex head width and 1½" overall length. The screws incorporate a No. 3 drill tip capable of penetrating materials up to 0.21" thickness. Manufactured to BSD tapping screw standards, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest industry requirements for hazardous substance restrictions and chemical safety.
