Professional Applications & Engineering Value
These No. 8 zinc-plated steel tapping screws are specifically engineered to address common challenges in sheet metal assembly operations. The thread forming technology eliminates the need for pre-tapped holes, creating stronger thread engagement while preventing metal shavings that can compromise electrical components or moving parts. The Phillips flat head design with standard profile ensures clean, flush installations that won't interfere with adjacent components. With a 0.164" thread diameter and fully threaded construction, these A/AB type screws provide exceptional pull-out resistance in materials up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
These tapping screws feature precision Class 2A thread tolerances with 15 TPI thread pitch and 0.164" thread diameter. Manufactured to A/AB tapping screw standards with right-hand threading and standard flat head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications.
