Professional Applications & Engineering Value
These 18-8 stainless steel sheet metal tapping screws deliver exceptional engineering value through their thread forming technology and corrosion-resistant properties. The Type A/AB thread forming design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads in sheet metal applications. The fully threaded shank ensures maximum grip length and pull-out resistance, while the pointed tip facilitates easy starting in pre-drilled holes. Manufactured from 18-8 stainless steel, these screws maintain integrity in demanding environments where moisture and chemicals are present. The square drive system prevents tool slippage during installation, reducing assembly time and improving worker safety. Ideal for HVAC systems, electrical enclosures, and metal fabrication where reliable sheet metal fastening is critical.
Specification Summary & Compliance
These precision No. 6 x 1-1/4" sheet metal tapping screws feature a 0.138" thread diameter with 18 threads per inch, designed for use in materials up to 0.025" thickness. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring they contain no restricted substances. Manufactured to precise dimensional tolerances with right-hand threading and fully threaded configuration, these Type A/AB thread forming screws provide consistent performance in industrial assembly applications.
