• Maximum thread engagement with full threading along the 1/2" length for reliable holding power in thin materials
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated industrial use
• Optimized for thin materials with precise No. 21 drill bit compatibility for 0.025" maximum thickness applications

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional performance in sheet metal applications where corrosion resistance is critical. The thread forming technology eliminates the need for tapping operations, creating strong, strip-resistant threads that won't loosen under vibration. The undercut flat head design ensures a flush finish while maximizing countersink contact, preventing head protrusion in precision assemblies. With 12 threads per inch and full threading, these screws provide maximum engagement in thin gauge materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and marine equipment where corrosion resistant fasteners are essential for long-term reliability.
