• Secure and easy drive engagement thanks to the square drive (No. 1 size), reducing cam-out and enabling high-torque application with standard tools.
• Optimized head design with a rounded pan style and standard profile, providing a low-profile finish and enhanced clamping force distribution.
• Consistent dimensional accuracy with right-hand threads, 0.138" diameter, and 20 threads per inch, ensuring reliable fit and repeatable assembly processes.
• Compliance with environmental standards including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These No. 6 BSD tapping screws are engineered to address common challenges in metal assembly, such as reducing labor time and minimizing component failure. Made from 410 stainless steel, they offer excellent strength and corrosion resistance, making them suitable for demanding applications in steel, stainless steel, and sheet metal industries. The thread forming design creates precise, durable threads without cutting, which enhances pull-out resistance and prevents loosening under vibration. The integrated drilling tip eliminates the need for separate drilling operations, streamlining production lines and reducing overall assembly costs. Ideal for HVAC, automotive, and machinery sectors, these screws ensure reliable performance in right-hand threaded fastening systems, backed by a pan head and square drive for secure installation.
