S-92525A121 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapped holes
• Optimized Phillips drive design ensures secure tool engagement and reduces cam-out during installation
• Full 32 TPI threading provides maximum thread engagement and superior holding power in thin materials
• Precision pan head profile offers low-profile installation with adequate bearing surface for secure fastening
• RoHS 3 compliance guarantees environmental responsibility and meets international regulatory standards
• Perfect material compatibility with recommended No. 48 drill bit (0.076") for optimal hole preparation and thread formation

Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for sheet metal applications where traditional fastening methods fall short. The 18-8 stainless steel composition provides exceptional corrosion resistance, making these screws ideal for outdoor equipment, electrical enclosures, and HVAC systems exposed to moisture and chemicals. The Type B thread forming design displaces material rather than removing it, creating stronger threads that resist vibration loosening and maintain integrity under stress cycles. The combination of 32 TPI fine threading and fully threaded shank ensures maximum grip in thin-gauge materials, while the Phillips pan head offers a balanced profile for both automated assembly and manual installation. This comprehensive engineering approach solves common industrial challenges of thread stripping, corrosion failure, and installation efficiency.

Specification Summary & Compliance

This No. 2 x 1/2" tapping screw features precision Class 2A thread tolerances with a thread diameter of 0.086" and fully threaded configuration. Manufactured to industry standards for Type B thread forming screws, it requires a No. 48 drill bit (0.076" diameter) for proper hole preparation. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring adherence to environmental regulations and making it suitable for global industrial applications requiring hazardous substance restriction compliance.
