S-90925A247 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum torque transmission and reduced cam-out with T25 Torx drive for reliable, high-torque installations
• Excellent thread-forming capability in sheet metal up to 0.025" thickness without requiring pre-tapped holes
• Secure, vibration-resistant fastening with fully threaded No. 10 design and 12 TPI precision for consistent holding power
• Wide bearing surface distribution from pan head design helps prevent surface damage and provides superior clamping force
• Streamlined assembly process with pointed tip for easy starting and alignment in sheet metal applications
• Compliance with international environmental standards including RoHS 3 and REACH for global manufacturing compatibility

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws are engineered specifically for sheet metal assembly challenges where traditional fastening methods fall short. The thread forming design creates strong, permanent threads in parent material without generating chips, eliminating contamination risks in sensitive applications. The T25 Torx drive system delivers exceptional torque transmission while minimizing tool slippage and fastener head damage during high-volume production runs. With fully threaded construction and 12 TPI precision, these screws provide uniform stress distribution and superior pull-out resistance in thin-gauge materials. The combination of zinc-plated corrosion protection and pan head configuration ensures reliable performance in HVAC systems, electrical enclosures, automotive components, and industrial equipment where vibration resistance and environmental durability are critical.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 10 thread diameter (0.19") with 12 TPI right-hand threading and Class 2A tolerance for consistent fit. The A/AB screw type is designed for use with No. 21 drill bit (0.159" diameter) in materials up to 0.025" thickness. Manufactured to industry standards for sheet metal applications, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the strictest international requirements for hazardous substance restrictions.
