Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments.
- Excellent thread-forming capability for secure, vibration-resistant fastening in sheet metal without pre-tapped holes.
- Efficient installation with Phillips No. 2 drive and pointed tip, reducing assembly time and tool slippage.
- Full threading design provides consistent grip along the entire 1-1/2" length, maximizing holding power in thin materials.
- Precise countersinking with an 82° flat head profile for a flush finish, minimizing protrusion and improving safety.
- Reliable compliance with RoHS 3 and REACH regulations, ensuring safe and sustainable use in global supply chains.
- Optimized for sheet metal with A/AB thread type and recommended No. 32 drill bit, preventing material damage and ensuring tight fits.
Professional Applications & Engineering Value
These No. 6 x 1-1/2" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as strip-out and loosening under vibration. The thread forming design creates strong, permanent threads in ductile materials, eliminating the need for nuts or washers and reducing assembly costs. With a Phillips flat head and fully threaded shank, they ensure uniform load distribution and a smooth surface finish, ideal for HVAC systems, electronic enclosures, and automotive panels. The zinc plating offers enhanced durability against rust, making these screws a reliable choice for high-volume production and harsh operational conditions.
Specification Summary & Compliance
This product features a thread diameter of 0.138" with 18 threads per inch and complies with standard Class 2A inch-series tolerances for consistent fit. The A/AB tapping screw type and right-hand threading adhere to industry norms for thread-forming applications. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are upheld for industrial use.
