S-95638A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Security: Tamper-resistant T25 Torx drive prevents unauthorized removal, ideal for public or high-security installations.
• Superior Corrosion Resistance: Made from 18-8 Stainless Steel for excellent durability in harsh environments, reducing maintenance and replacement costs.
• Optimized for Sheet Metal: Thread forming design creates strong, permanent threads in sheet metal up to 0.025" thick without pre-tapping, saving time and labor.
• Secure Fastening: Fully threaded shank and pointed tip ensure maximum thread engagement and easy starting for a reliable, vibration-resistant hold.
• Standardized Compatibility: Conforms to A/AB tapping screw standards and is designed for use with a standard No. 21 drill bit (0.159"), ensuring easy integration into existing workflows.
• High-Strength Performance: No. 10-12 thread configuration with a 0.19" diameter provides a robust grip and high clamp load for demanding sheet metal applications.

Professional Applications & Engineering Value

This tapping screw is specifically engineered for sheet metal fabrication, addressing common challenges like material stripping and weak thread engagement. Its thread forming action cold-forms the material, creating stronger threads than traditional cutting screws and eliminating metal chips that can cause electrical shorts or contamination. The 18-8 Stainless Steel construction ensures long-term corrosion resistance, making it suitable for outdoor enclosures, HVAC systems, and electronic chassis. The tamper-resistant Torx T25 drive is crucial for public infrastructure, vending machines, and security panels, preventing vandalism and unauthorized access. The pointed tip and fully threaded design guarantee quick starts and maximum holding power in thin-gauge metals, streamlining assembly and enhancing joint integrity.
