S-93945A062 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Exceptional holding power through fully threaded design and thread forming technology that creates stronger, more secure connections in sheet metal
• Enhanced torque transmission with square drive design that prevents cam-out and allows for higher installation torque
• Flush surface finish with standard 82° flat head profile that sits perfectly countersunk for smooth, professional applications
• Optimized for sheet metal with pointed tip and A/AB thread design that eliminates the need for pre-tapped holes
• Reliable dimensional consistency with precise No. 12 size and 2-1/2" length for uniform performance across production runs
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable industrial use

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional engineering value for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology creates permanent, high-strength threads in base materials without generating chips, eliminating contamination risks in sensitive assemblies. The square drive system provides superior torque transmission compared to traditional drives, reducing installation time and preventing tool slippage that can damage fastener heads. With full threading along the entire 2-1/2" length and precise 82° flat head profile, these screws ensure maximum thread engagement and flush mounting in panels, enclosures, and structural components. The combination of 0.216" thread diameter and 11 threads per inch delivers optimal pull-out resistance while maintaining material integrity in thin-gauge metals up to 0.025" thickness.

Specification Summary & Compliance

These No. 12 x 2-1/2" tapping screws feature precision thread forming design with A/AB tapping screw type and right-hand threading. The screws maintain dimensional accuracy with 0.216" thread diameter and 11 threads per inch specifications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring they meet the latest regulatory requirements for industrial fastener applications. The standard 82° countersink angle matches industry-standard tooling for consistent installation performance.
