S-90048A253 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Effortless installation through thread-forming technology that creates strong, permanent threads without pre-tapping
• Optimal flush mounting with standard 82° flat head profile that sits perfectly countersunk in sheet metal applications
• Enhanced driving efficiency with No. 2 Phillips drive that minimizes cam-out and ensures secure fastening control
• Maximum material penetration through fully threaded design and pointed tip for reliable engagement in sheet metal up to 0.025" thickness
• Precise compatibility with No. 21 drill bits (0.159" diameter) for accurate hole preparation and optimal thread formation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 10 x 2" zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming A/AB type design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, vibration-resistant connections. The Phillips flat head configuration with 82° countersink angle provides a clean, flush finish that prevents snagging and maintains aerodynamic surfaces in HVAC systems, electronic enclosures, and automotive panels. The combination of 12 TPI thread pitch and pointed tip ensures rapid penetration and secure fastening in thin-gauge materials, making these industrial screws ideal for high-volume production environments where reliability and efficiency are paramount.

Specification Summary & Compliance

These tapping screws feature precise inch system dimensions including No. 10 thread diameter (0.19"), 2" length, and Class 2A thread tolerances for consistent performance. Manufactured to industry standards for A/AB type thread forming screws with right-hand threading and standard flat head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
