Professional Applications & Engineering Value

These No. 2 x 5/16" Black-Oxide 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 tapping operations, creating strong internal threads while preventing material cracking in sheets up to 0.025" thickness. The Phillips pan head configuration ensures uniform clamping force distribution, while the Black-Oxide finish provides essential corrosion protection in industrial environments. These A/AB type screws with their 32 TPI precision threading deliver exceptional pull-out resistance, making them ideal for electronics enclosures, HVAC systems, automotive components, and machinery assemblies where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 2 size with 0.086" thread diameter and 5/16" length, manufactured to precise Class 2A thread tolerances for consistent performance. The A/AB tapping screw type follows industry-standard thread forms for sheet metal applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets. The specified No. 48 drill bit (0.076" diameter) provides optimal hole preparation for maximum thread engagement and holding strength.
