Professional Applications & Engineering Value
These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening in thin materials is critical. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume manufacturing. The Phillips drive system provides consistent torque transmission while the fully threaded configuration ensures maximum pull-out resistance in materials up to 0.025" thickness. Ideal for HVAC systems, electronic enclosures, and automotive components, these A/AB type screws create durable, vibration-resistant threads that maintain integrity under dynamic loads and thermal cycling conditions common in industrial environments.
Specification Summary & Compliance
This No. 6 x 3/8" tapping screw features a 0.138" thread diameter with 18 TPI precision threading and standard Class 2A thread tolerances. The screw is designed for use with No. 32 drill bits (0.116" diameter) and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global manufacturing and export requirements. The right-hand thread direction and thread forming tapping method provide reliable performance in standard sheet metal fabrication applications.
