Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Effortless installation and secure fastening through thread forming design that creates strong, permanent threads in sheet metal without pre-tapping.
- Flush, professional finish with a standard flat head and 82° countersink angle, ideal for applications requiring a smooth surface.
- Reliable drive engagement with Phillips No. 2 drive, reducing cam-out risk and ensuring consistent torque application.
- Optimized for thin materials, capable of drilling up to 0.025" thickness with compatible No. 32 drill bit for precise assembly.
- Full-threaded design provides maximum grip and holding power along the entire 7/8" length in sheet metal joints.
- Compliance with global environmental standards, including RoHS 3 and REACH, ensuring safe use in regulated industries.
Professional Applications & Engineering Value
These zinc-plated steel tapping screws are engineered to address common challenges in sheet metal assembly, such as material splitting and loose fasteners. The thread forming technology displaces material rather than cutting it, creating stronger threads with improved resistance to vibration loosening. The Phillips flat head design ensures a clean, flush installation that minimizes protrusion in HVAC systems, electronic enclosures, and automotive panels. With a 0.138" thread diameter and 18 TPI, these A/AB type screws deliver reliable performance in thin-gauge metals, reducing assembly time and enhancing structural integrity for industrial and construction applications.
Specification Summary & Compliance
This product adheres to standard inch measurements with a No. 6-18 thread size and 7/8" length, featuring a right-hand thread direction and fully threaded shank. It conforms to typical thread forming screw specifications for sheet metal, including compatibility with a No. 32 drill bit (0.116" diameter). The screws are manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring they are free from hazardous substances and suitable for global supply chains.
