Key Features & Benefits at a Glance
- Superior corrosion resistance with 410 stainless steel construction, ensuring long-lasting performance in harsh industrial environments.
- Efficient self-drilling capability with a No. 3 drill tip, allowing for quick penetration in steel, stainless steel, and sheet metal up to 0.14" thick without pre-drilling.
- Secure fastening with thread forming design (BSD type), creating strong, vibration-resistant threads in metal substrates for reliable hold.
- Easy installation and reduced tool wear thanks to the Phillips drive style and standard flat head with 82° countersink angle for flush, professional finishes.
- Full threading along the 4-inch length provides consistent grip and adjustability in various material thicknesses.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
- Precise right-hand thread with 14 TPI and standard dimensions for compatibility with common industrial applications.
Professional Applications & Engineering Value
These No. 12 tapping screws are engineered to address common challenges in metalworking, such as time-consuming pre-drilling and thread stripping. Made from 410 stainless steel, they offer excellent strength and resistance to oxidation, making them ideal for steel, stainless steel, and sheet metal applications in construction, HVAC, and automotive assembly. The thread forming (BSD) design cold-forms threads into the material, reducing stress and improving fatigue resistance compared to thread-cutting alternatives. Combined with a drilling tip and Phillips flat head, these screws streamline installation, minimize labor costs, and ensure a secure, flush fit in demanding environments.
Specification Summary & Compliance
This product adheres to standard inch measurements with a thread diameter of 0.216" and 14 threads per inch, typical for No. 12 screw sizes. The flat head features an 82° countersink angle for seamless integration. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and durability for industrial use.
