Professional Applications & Engineering Value
This 316 stainless steel Phillips flat head tapping screw delivers exceptional performance in demanding sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming design (A/AB type) eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, reliable threads that resist loosening under vibration. The combination of full threading and precise 82° countersink angle ensures flush mounting in panels and enclosures, providing both aesthetic appeal and protection against snagging. Particularly valuable in industrial equipment, marine hardware, and outdoor structures, these screws maintain their mechanical properties and corrosion resistance even in saltwater environments, making them an engineering solution for long-term reliability in challenging conditions.
Specification Summary & Compliance
This No. 10-12 x 1-1/2" tapping screw features Class 2A thread tolerances with 12 threads per inch and standard flat head profile according to industry specifications. The screw is manufactured to A/AB tapping screw standards for thread forming applications in sheet metal. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance management, meeting current industry requirements for sustainable manufacturing practices.
