S-94059A313 12-24 x 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Integrated sealing protection through steel/rubber washer prevents moisture ingress and maintains joint integrity
• Efficient installation with drilling tip design that penetrates up to 1/2" thickness without pre-drilling
• Enhanced driving torque with external hex drive and hex head design for secure fastening in high-vibration applications
• Reliable thread engagement through UNC coarse thread spacing and full threading for maximum holding power
• Optimized for steel and sheet metal applications with thread-forming (CSD) design that creates strong, permanent threads
• Consistent performance with right-hand thread direction and standardized 12-24 thread size for predictable results

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in industrial fastening applications where moisture resistance and structural integrity are critical. The thread-forming CSD design eliminates the need for tapped holes while creating durable threads in steel and sheet metal substrates. The integrated steel/rubber sealing washer provides reliable environmental sealing, preventing corrosion and maintaining joint integrity in outdoor or high-humidity environments. With the drilling tip capable of penetrating up to 1/2" thickness, these screws significantly reduce installation time and labor costs in assembly operations. The UNC coarse thread spacing ensures rapid installation and superior pull-out resistance, making them ideal for heavy-duty industrial applications where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This 12-24 thread forming screw features UNC coarse thread spacing with standard Class 2A thread tolerances for consistent performance. The 1-1/2" length and No. 12 screw size provide optimal fastening capability for various material thicknesses. Manufactured to industry standards for tapping screws, the product incorporates a flat washer design with 0.563" OD and utilizes No. 5 drill tip geometry for maximum penetration efficiency. The construction complies with relevant industrial fastening specifications and environmental regulations for industrial applications.
