S-97899A613 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient self-drilling capability with a No. 3 drill tip that eliminates pre-drilling, saving significant labor time and costs in steel, stainless steel, and sheet metal assemblies.
• Enhanced driving torque and tool engagement provided by the external hex head design, ensuring secure installation and reducing the risk of stripping.
• Maximum material penetration with the ability to drill through up to 0.187" thickness, offering reliable fastening in various metal gauges.
• Excellent thread retention and vibration resistance from the thread forming (BSD) design, which creates strong, lasting threads without chips.
• Increased load distribution and stability due to the integrated flange, minimizing surface damage and providing a secure, flush fit.
• Durable, corrosion-inhibiting finish with a white painted head that adds an extra layer of protection and allows for easy visual inspection.

Professional Applications & Engineering Value

These No. 12 self-drilling tapping screws are engineered to address common challenges in metal fabrication and construction, such as the need for rapid installation and high pull-out strength. Made from 410 stainless steel, they offer excellent resistance to oxidation and corrosion, making them suitable for HVAC systems, electrical enclosures, and structural steel assemblies. The thread forming (BSD) design and fully threaded shank ensure superior holding power by displacing material rather than cutting it, which reduces failure risks in vibrating environments. The external hex drive allows for high-torque application with standard tools, speeding up assembly lines while the self-drilling tip penetrates up to 0.187" of steel or sheet metal without pilot holes, streamlining workflows and reducing overall project costs.

Specification Summary & Compliance

This fastener features a No. 12 screw size with a 0.216" thread diameter and 14 threads per inch in a right-hand thread direction. It is fully threaded and includes a flange with a 0.432" diameter for improved load distribution. Manufactured to common industrial standards for tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various international markets.
