S-90628A335 12-24 x 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with specialized coating extends service life in harsh industrial environments
• Integrated steel/rubber sealing washer creates reliable moisture and dust barriers in assembled components
• Self-drilling tip design eliminates pre-drilling requirements, reducing installation time by up to 1/2" material thickness
• Thread forming UNC coarse threads provide exceptional pull-out resistance in steel and sheet metal applications
• External hex drive with hex head ensures secure tool engagement and high torque transmission during installation
• Full threading along 2" length delivers maximum grip strength and uniform stress distribution
• RoHS 3 compliance meets international environmental standards for industrial manufacturing

Professional Applications & Engineering Value

This 12-24 UNC thread forming tapping screw addresses critical challenges in metal fabrication and assembly operations. The corrosion-resistant coated steel construction combined with the steel/rubber sealing washer provides dual protection against environmental degradation and fluid ingress, making it ideal for outdoor equipment, HVAC systems, and electrical enclosures. The thread forming design creates stronger mating threads in steel and sheet metal substrates by displacing material rather than removing it, resulting in improved fatigue resistance and vibration performance. The integrated drilling tip streamlines installation in production environments, eliminating secondary drilling operations while maintaining UNC coarse thread integrity up to 1/2" material thickness.

Specification Summary & Compliance

Manufactured to precise UNC thread standards with No. 12 screw size and 2" fully threaded length. Features Class 2A thread tolerances for reliable mating compatibility. The external hex drive with 0.313" head width ensures standard tool compatibility. Compliant with RoHS 3 (2015/863/EU) regulations for restricted substance management. Designed for optimal performance in steel and sheet metal applications with maximum drilling capacity of 1/2" thickness using No. 5 drill tip geometry.
