Professional Applications & Engineering Value
These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and reliable fastening are critical. The thread forming Type A/AB design eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening and provide exceptional pull-out strength. The undercut oval head with 82° countersink angle ensures a flush finish that enhances both aesthetics and safety in assembled products. Ideal for HVAC systems, electrical enclosures, and metal fabrication projects, these Phillips drive screws deliver consistent performance in materials up to 0.025" thickness, making them perfect for joining thin gauge metals without compromising structural integrity.
Specification Summary & Compliance
Manufactured to precise inch system specifications with No. 12 screw size, 1/2" length, 0.216" thread diameter, and 11 threads per inch.
