• Optimized pan head design provides excellent bearing surface and facilitates easy installation with standard slotted drivers
• Precise dimensional compatibility with No. 21 drill bits (0.159") ensures proper fit and maximum holding power in sheet metal applications
• Full threading along the entire 1/2" length delivers consistent clamping force and superior pull-out resistance
• Right-hand thread direction with 12 TPI configuration ensures smooth installation and reliable performance in automated assembly processes
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global industrial applications and environmental safety

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The thread forming A/AB type design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, vibration-resistant connections. The slotted pan head configuration provides excellent torque transmission and a low-profile finish ideal for applications where clearance is limited. With full threading and pointed tip, these screws penetrate smoothly and maintain consistent clamping force across the entire 1/2" length, preventing material distortion and ensuring long-term joint integrity in HVAC systems, electrical enclosures, and industrial equipment manufacturing.

Specification Summary & Compliance

These tapping screws feature precise No. 10 size with 0.19" thread diameter and 12 threads per inch configuration, manufactured to industry standards for thread forming applications. The zinc-plated steel construction provides consistent performance with 0.373" head diameter and standard pan head profile. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets. Recommended for use with No. 21 drill bits (0.159" diameter) in sheet metal up to 0.025" maximum drilling thickness.
