S-94058A321 12-24 x 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated 410 stainless steel construction, ideal for harsh industrial environments
• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 1/2" thickness in stainless steel and sheet metal
• Enhanced weatherproof sealing through integrated stainless steel/rubber washer that prevents moisture and contaminant ingress
• High-strength thread forming capability with UNC coarse threads that create strong, permanent fastenings in tough materials
• Secure installation and removal with external hex drive design that provides superior torque transmission and prevents stripping
• Full-length threading ensures maximum grip and load distribution across the entire fastener length
• Compliance with environmental regulations including RoHS 3 and REACH for safe, sustainable industrial use

Professional Applications & Engineering Value

These 12-24 UNC thread forming screws deliver exceptional engineering value in demanding industrial applications where corrosion resistance and weatherproof performance are critical. The zinc-plated 410 stainless steel construction provides superior protection against rust and chemical exposure, while the integrated sealing washer creates a reliable barrier against moisture and environmental contaminants. The drilling tip design eliminates the need for pre-drilling operations, significantly reducing installation time and labor costs when working with stainless steel and sheet metal applications up to 1/2" thickness. The external hex drive ensures secure torque application during installation, preventing fastener failure in high-vibration environments common in industrial machinery, outdoor equipment, and structural assemblies.

Specification Summary & Compliance

This tapping screw features precision 12-24 UNC coarse threads with thread forming design (CSD type) that creates strong, permanent fastenings.
