Professional Applications & Engineering Value

These 316 Stainless Steel Phillips oval head tapping screws deliver exceptional value in demanding sheet metal applications where corrosion resistance and joint integrity are critical. The thread forming design eliminates the risk of metal chips contaminating sensitive equipment while creating stronger threads than traditional cutting screws. The fully threaded No. 8 configuration provides maximum pull-out resistance in thin materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive panels. The combination of 15 threads per inch precision and 0.164" thread diameter ensures reliable performance in various gauge metals, while the oval head profile offers both aesthetic appeal and functional countersinking capability.

Specification Summary & Compliance

These A/AB type thread forming screws feature standard inch measurements with Class 2A thread tolerances for consistent fit and performance. The screws maintain precise dimensions including 1" length, 0.312" head diameter, and 15 threads per inch count. Manufacturing complies with industry standards for tapping screws and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety requirements for industrial fastener applications.
