S-90190A083 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Superior thread-forming capability with A/AB tapping design creates precise, durable threads without pre-tapping in sheet metal
• Optimized drive efficiency through Phillips No. 1 drive style provides reliable torque transfer and reduces cam-out during installation
• Maximum material engagement with fully threaded 32 TPI design ensures superior holding power in thin sheet metal applications
• Streamlined assembly process with pointed tip and standard pan head profile for quick starts and flush seating
• Precision dimensional control with 0.086" thread diameter and 1/2" length maintains consistent performance across production runs
• Environmental compliance assurance with RoHS 3 certification meets global regulatory standards for hazardous substance restrictions

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws deliver exceptional value in sheet metal assembly applications where vibration resistance and material integrity are critical. The thread forming design eliminates the need for pre-tapped holes, reducing labor costs and potential thread damage during installation. The zinc-plated steel construction provides reliable corrosion protection while maintaining the high tensile strength required for structural applications. With 32 TPI precision threading and Phillips drive compatibility, these screws ensure consistent clamping force distribution across joined materials, preventing loosening under dynamic loads. The combination of 0.086" thread diameter and fully threaded design maximizes pull-out resistance in thin-gauge materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive components where reliable metal fastening is essential.

Specification Summary & Compliance

These tapping screws feature precision Class 2A thread tolerances with 0.086" thread diameter and 32 TPI thread pitch. Manufactured to A/AB tapping screw standards with right-hand threading and fully threaded configuration. Compliance includes RoHS 3 (2015/863/EU) regulations, ensuring adherence to hazardous substance restrictions for global industrial applications. The screws are engineered for use with No. 48 drill bit (0.076" diameter) and are optimized for sheet metal applications with maximum drilling thickness of 0.025".
