Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are engineered specifically for steel and sheet metal applications where reliability and efficiency are paramount. The thread-forming BSD design eliminates the need for separate tapping operations, creating strong internal threads that resist vibration loosening. The integrated No. 3 drill tip penetrates up to 0.21" thick materials while the 82° flat head profile sits flush for safety and aesthetics. The zinc-plated finish provides essential corrosion protection in industrial environments, making these fully threaded screws ideal for construction, metal fabrication, and equipment assembly where durable fastening solutions are required.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.216" thread diameter and 14 threads per inch in right-hand orientation. Features Class 2A thread tolerances and complies with BSD tapping screw specifications. The standard flat head profile with 0.412" head diameter ensures proper seating in prepared holes. These thread-forming screws meet industrial fastening standards for material compatibility and performance in steel and sheet metal applications.
