Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Efficient thread forming action creates strong, permanent threads in sheet metal, eliminating the need for pre-tapped holes.
- High-torque Phillips drive (No. 1 size) ensures secure installation and reduces the risk of cam-out for reliable fastening.
- 32 TPI fine threading provides excellent grip and vibration resistance in thin sheet metal applications.
- Fully threaded 5/8" length offers maximum engagement and holding power across the entire fastener.
- Standard pan head design with a rounded profile for a low-profile, finished appearance and easy wrenching.
- Comprehensive compliance with RoHS 3 and REACH regulations ensures safety and environmental responsibility.
Professional Applications & Engineering Value
These No. 2 thread forming tapping screws are engineered to solve critical fastening challenges in sheet metal assemblies. The zinc-plated steel material provides a durable barrier against rust, essential for longevity in industrial settings. The A/AB Type thread-forming design displaces material to create a zero-clearance fit, which resists loosening under vibration—a common failure point in machinery and enclosures. The Phillips drive and pointed tip facilitate quick, aligned starts, speeding up production lines. This combination of precision threading and robust construction delivers reliable performance in HVAC systems, electronic chassis, and automotive panels, reducing assembly time and maintenance costs.
Specification Summary & Compliance
This screw features a No. 2 screw size with a thread diameter of 0.086" and a Class 2A unified thread standard for reliable fit. The fully threaded design and right-hand thread direction ensure consistent performance. It is manufactured to be used with a No. 48 drill bit (0.076" diameter) for optimal thread formation in materials up to 0.025" thick. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting stringent industry standards for hazardous substance restrictions.
