Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- Enhanced torque transmission and reduced cam-out thanks to the Torx T10 drive system for more secure installations
- Reliable thread-forming action creates strong, permanent threads in sheet metal without the need for pre-tapped holes
- Full-length threading ensures maximum grip and holding power along the entire 3/8" length for secure sheet metal assemblies
- Streamlined procurement and compliance with RoHS 3 and REACH regulations, meeting international environmental standards
- Optimized for No. 44 drill bits (0.086" diameter) for precise, clean hole preparation in sheet metal up to 0.025" thick
- Wide industrial compatibility as standard A/AB type thread forming screws with right-hand threading for common applications
Professional Applications & Engineering Value
These No. 4-24 thread forming screws are specifically engineered to solve critical fastening challenges in sheet metal applications. The zinc-plated steel construction provides essential corrosion protection where metal components are exposed to environmental factors, while the Torx T10 drive prevents tool slippage and damage to fastener heads during high-torque assembly operations. The thread forming design displaces material rather than cutting it, creating stronger threads with improved resistance to vibration loosening. The pan head style offers a low-profile yet secure bearing surface, making these tapping screws ideal for electronics enclosures, HVAC systems, and automotive panels where reliable, permanent fastening is paramount.
Specification Summary & Compliance
These screws feature a No. 4-24 thread size with standard Class 2A thread tolerances and fully threaded construction. Manufactured as A/AB type thread forming screws with right-hand threading, they comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The specified No. 44 drill bit (0.086" diameter) ensures proper hole preparation for optimal performance in sheet metal applications.
