S-94195A346 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel material, ideal for harsh industrial environments and extending service life.
• Efficient self-drilling capability with a No. 3 drill tip, eliminating the need for pre-drilling and speeding up assembly in steel and sheet metal.
• Strong, reliable fastening through thread forming (BSD type), creating durable threads in materials like stainless steel and sheet metal.
• Secure flush installation with a standard flat head and 82° countersink angle, providing a smooth surface finish and reducing snagging risks.
• Easy installation with Phillips No. 3 drive, allowing for common tool use and reducing slippage during tightening.
• Full thread engagement along the 2 1/2" length, ensuring maximum grip and load distribution in various metal thicknesses.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in global industrial supply chains.

Professional Applications & Engineering Value

These 1/4"-14 tapping screws are engineered to address common challenges in metal fabrication, such as time-consuming pre-drilling and corrosion-induced failures. The 410 Stainless Steel construction offers excellent strength and resistance to rust, making them suitable for outdoor or humid conditions in steel, stainless steel, and sheet metal assemblies. The thread forming (BSD) design cold-forms threads as it's driven, reducing material stress and providing vibration resistance. With a fully threaded shank and drilling tip, they penetrate up to 0.21" thickness efficiently, streamlining production lines and reducing labor costs. Ideal for HVAC, automotive, and construction applications, these screws deliver reliable performance where durability and regulatory compliance are critical.

Specification Summary & Compliance

This product adheres to standard inch measurements with a 1/4" thread diameter and 14 threads per inch, ensuring precise fits in thread forming applications. The flat head profile and Phillips drive are designed for common industrial use, while the 82° countersink angle meets typical flush-mounting requirements. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe, global industrial deployment.
