Professional Applications & Engineering Value
This black-oxide steel thread forming screw addresses critical challenges in sheet metal fabrication and assembly operations. The A/AB tapping screw type with thread forming technology eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger, more reliable threads in metal substrates. The fully threaded design ensures consistent engagement across the entire 7/8" length, providing superior pull-out resistance in thin-gauge materials. The black-oxide surface treatment offers enhanced corrosion protection, making these Phillips oval head screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This No. 10 thread forming screw features precision 0.19" thread diameter with 12 threads per inch and standard Class 2A thread tolerances. The oval head profile with 82° countersink angle ensures proper seating in prepared holes. Manufactured to industry standards for sheet metal fastening applications, this product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial users.
