Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide Steel coating, extending service life in demanding industrial environments
- Enhanced holding power through thread forming design that creates strong, permanent threads in sheet metal without pre-tapping
- Flush, professional finish with oval head and 82° countersink angle that sits neatly in prepared holes
- Reliable drive engagement with Phillips No. 2 drive style for secure installation and reduced cam-out risk
- Full 2-inch threading coverage ensures maximum grip length and uniform stress distribution
- Precision compatibility with No. 29 drill bits (0.136" diameter) for optimal hole preparation
- Regulatory compliance with RoHS 3 and REACH standards for safe, environmentally responsible manufacturing
Professional Applications & Engineering Value
These No. 8 thread forming tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The Black-Oxide Steel construction provides superior corrosion protection, while the thread forming design (A/AB type) displaces material rather than removing it, creating stronger threads with improved fatigue resistance. The Phillips oval head with 82° countersink angle ensures a flush finish that eliminates snagging points in assembled components. With 15 TPI thread pitch and 0.164" thread diameter, these screws maintain consistent clamping force across the full 2-inch length, making them ideal for HVAC systems, electrical enclosures, and metal fabrication where reliable, long-term fastening is essential.
Specification Summary & Compliance
These thread forming tapping screws feature precision No. 8 screw size with 0.164" thread diameter and 15 TPI thread pitch, designed for maximum drilling thickness of 0.025". The oval head profile with 82° countersink angle ensures proper seating in prepared holes. Manufactured to industry standards for tapping screws with right-hand threading and fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
