S-94059A315 12-24 x 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments
• Effortless installation through self-drilling No. 5 tip design that eliminates pre-drilling and penetrates up to 1/2" thickness
• Enhanced sealing performance with integrated steel/rubber washers that prevent moisture and debris ingress
• Maximum torque transmission via external hex drive design that prevents stripping during high-torque applications
• Exceptional holding power with fully threaded UNC coarse thread design that provides superior grip in steel and sheet metal
• Reduced assembly time through thread-forming CSD design that creates strong, permanent threads without tapping operations
• Reliable fastening performance with flat washer design that distributes load evenly and prevents surface damage

Professional Applications & Engineering Value

These 12-24 zinc-plated steel tapping screws deliver exceptional engineering value for demanding steel and sheet metal applications. The thread-forming CSD design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume production environments. The integrated No. 5 drilling tip penetrates up to 1/2" thickness without pre-drilling, preventing material deformation and ensuring precise fastener placement. The steel/rubber sealing washer provides critical protection against environmental contaminants, making these UNC coarse thread screws ideal for outdoor equipment, HVAC systems, and automotive assemblies where moisture resistance is paramount. The external hex drive configuration ensures reliable torque transmission, preventing cam-out and ensuring consistent clamping force in automated assembly processes.

Specification Summary & Compliance

These 12-24 UNC coarse thread tapping screws maintain precision Class 2A thread tolerances for consistent performance across industrial applications. Manufactured to industry standards for thread-forming CSD screws, they feature a 0.216" thread diameter with fully threaded design and right-hand thread direction. The 0.563" OD flat washer and zinc-plated steel construction comply with industrial corrosion resistance requirements. These fasteners are engineered to meet relevant industry specifications for sheet metal and steel applications and conform to standard dimensional requirements for No. 12 screw sizes with 2" length configurations.
