Professional Applications & Engineering Value

These No. 10 x 1" 316 stainless steel oval head Phillips tapping screws deliver exceptional engineering value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates common issues with traditional tapping methods by creating stronger, more reliable threads through material displacement rather than cutting. This approach prevents metal fatigue and maintains the integrity of thin sheet metal substrates up to 0.025" thickness. The combination of 316 stainless steel material and A/AB thread forming design ensures reliable performance in demanding environments, from outdoor enclosures to marine applications, where exposure to moisture and chemicals would compromise ordinary fasteners. The oval head profile with 82° countersink angle provides a flush finish that enhances both aesthetics and safety in visible applications.

Specification Summary & Compliance

These thread forming tapping screws feature precise No. 10 screw size with 0.19" thread diameter and 12 threads per inch in right-hand orientation. The fully threaded design ensures maximum engagement, while the pointed tip facilitates easy starting in pre-drilled holes. Manufacturing complies with A/AB tapping screw standards for thread forming applications. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, ensuring environmentally responsible production and chemical safety for industrial applications.
