• Reliable Phillips drive system (No. 1 size) provides excellent torque transfer and reduces cam-out during high-volume assembly operations
• Fully threaded shank design maximizes grip length and pull-out resistance for superior fastening integrity in thin materials
• RoHS 3 compliance ensures environmental responsibility and meets international regulatory standards for hazardous substance restrictions
• Standard pan head profile offers low-profile installation with good bearing surface for secure fastening without sinking

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly applications where reliability and efficiency are critical. The thread forming (Type A/AB) design eliminates the need for separate tapping operations, significantly reducing production time while creating strong, vibration-resistant connections. The combination of 0.086" thread diameter with 32 TPI fine threading provides excellent holding power in thin-gauge materials up to 0.025" thickness. The zinc plating surface treatment offers essential corrosion protection for industrial environments, while the Phillips drive system ensures consistent installation torque in high-volume manufacturing settings. These sheet metal fasteners are engineered to prevent stripping and maintain joint integrity in automotive, electronics enclosure, and HVAC applications where reliable mechanical fastening is paramount.
