• Efficient installation with No. 2 Phillips drive and pointed tip, reducing assembly time and effort.
• Clean, finished appearance provided by the standard oval head, which sits flush when installed.
• Wide material compatibility for use in sheet metal up to 0.025" thickness, with recommended No. 21 drill bit for precise hole preparation.
• Reliable performance with 12 threads per inch and A/AB type, ensuring consistent, vibration-resistant connections.
• Compliance with environmental regulations including RoHS 3 and REACH, making it suitable for global industrial supply chains.

Professional Applications & Engineering Value

This No. 10 thread forming tapping screw is engineered to solve common fastening challenges in sheet metal fabrication. The Black-Oxide Steel construction provides a protective layer that resists rust and corrosion, crucial for maintaining integrity in varied environmental conditions. Its thread forming (not cutting) action displaces material to create a strong, zero-clearance fit, eliminating the need for pre-tapped holes and reducing the risk of loose connections under vibration. The combination of a Phillips drive and oval head offers both efficient torque transmission and a smooth, low-profile finish, ideal for applications in HVAC systems, electronic enclosures, and automotive panels where both performance and aesthetics matter. The fully threaded design ensures maximum grip length, providing superior pull-out strength compared to partially threaded alternatives.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 10 screw size, 3/4" length, and 0.19" thread diameter. It features a standard oval head profile with an 82° countersink angle and is designed as an A/AB type tapping screw for thread forming applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent international standards for hazardous substance restrictions and chemical safety in industrial components.
