S-90054A240 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments
• Enhanced torque transmission through the external hex/slotted drive design, allowing for secure installation and removal
• Efficient thread forming in sheet metal applications, reducing the need for pre-tapped holes and speeding up assembly
• Integrated flange design provides a wider bearing surface, distributing load evenly and preventing pull-through in thin materials
• Full threading along the 3/8" length ensures maximum grip and holding power in sheet metal up to 0.025" thickness
• Precise compatibility with No. 21 drill bit (0.159" diameter), simplifying hole preparation and reducing installation errors
• Compliance with environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and global supply chains

Professional Applications & Engineering Value

These No. 10-12 zinc-plated steel flanged hex tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The thread forming design creates strong, permanent threads in ductile materials without generating chips, minimizing debris in sensitive assemblies. The flanged head eliminates the need for separate washers, reducing part count and assembly time while providing a secure, vibration-resistant connection. Ideal for HVAC systems, electrical enclosures, and automotive panels, these fully threaded screws ensure consistent clamping force across the entire engagement length, preventing loosening under dynamic loads. The external hex/slotted drive offers flexibility for both manual and powered tools, enhancing productivity in high-volume manufacturing environments.

Specification Summary & Compliance

This No. 10 tapping screw features a right-hand thread with approximately 12 threads per inch and a pointed tip for easy starting. Manufactured to A/AB tapping screw type standards, it ensures reliable performance in sheet metal applications. The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use without hazardous substances.
