S-92525A213 Length 3/4" 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
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs
• Optimized Phillips No. 1 drive provides secure tool engagement and reduces cam-out risk during high-torque installation
• Fully threaded blunt tip design ensures maximum grip length and prevents material splitting in thin sheet applications
• Precision 24 TPI thread profile delivers superior holding power and vibration resistance in metal assemblies
• Compliant with RoHS 3 and REACH regulations for safe use across global markets and environmentally sensitive applications
• Standard pan head profile offers excellent bearing surface for secure fastening while maintaining a low-profile appearance

Professional Applications & Engineering Value

These Type B thread forming screws are engineered specifically for sheet metal applications where reliability and corrosion resistance are paramount. The 18-8 stainless steel composition provides exceptional durability against oxidation and chemical exposure, making these tapping screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming technology displaces material rather than removing it, creating stronger threads with improved fatigue resistance compared to cutting screws. The Phillips pan head design with No. 1 drive size ensures consistent installation torque transfer, while the fully threaded blunt tip prevents material piercing in thin-gauge metals. This combination of features addresses common industrial challenges including vibration loosening, corrosion failure, and installation efficiency in high-volume manufacturing environments.

Specification Summary & Compliance

This No. 4 x 3/4" tapping screw features a 0.112" thread diameter with 24 threads per inch precision and Class 2A thread tolerances for consistent performance. The Type B thread forming design follows industry standards for sheet metal fastening applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial use. The screw is designed for use with No. 44 drill bits (0.086" diameter) and features a rounded pan head with 0.219" diameter and 0.08" height for optimal clamping force distribution.
