S-94059A265 12-24 x 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.21" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in demanding environments
• Weatherproof sealing capability with integrated steel/rubber washer that prevents moisture and contaminant ingress
• High-strength thread forming design creates permanent, vibration-resistant threads in parent material without chip removal
• Optimized installation efficiency with external hex drive and UNC coarse threads for faster assembly and reduced labor costs
• Full-length threading ensures maximum grip length and uniform load distribution across the entire fastener
• Industry-standard compatibility with CSD tapping screw specifications for reliable performance in industrial applications

Professional Applications & Engineering Value

Engineered for steel and sheet metal fabrication, these 12-24 thread forming screws deliver exceptional value in industrial assembly operations. The zinc-plated steel construction provides reliable corrosion protection, while the integrated steel/rubber sealing washer creates an effective barrier against environmental elements—eliminating the need for separate sealing components. The drilling tip design significantly reduces installation time by penetrating materials up to 0.21" thick without pre-drilling, minimizing labor costs and production delays. As CSD tapping screws with UNC coarse threads, they offer superior pull-out resistance and vibration durability in demanding applications, making them ideal for HVAC systems, electrical enclosures, and metal building components where reliable, weatherproof fastening is critical.
