Professional Applications & Engineering Value

These No. 8 x 1" oval head tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and corrosion protection are critical. The 18-8 stainless steel composition provides lasting durability against moisture and chemicals, while the thread forming design eliminates the need for tapping operations by creating precise mating threads through material displacement. This results in stronger connections with reduced installation time and superior pull-out resistance. The fully threaded configuration ensures maximum grip length, making these Phillips drive screws ideal for HVAC systems, electronic enclosures, and automotive components where reliable fastening in thin materials is essential.

Specification Summary & Compliance

These screws feature a 0.164" thread diameter with 15 threads per inch and standard Class 2A thread tolerances for consistent performance. Manufactured as A/AB type tapping screws with right-hand threading and pointed tip for easy starting. The oval head profile measures 0.312" diameter with 0.152" head height, designed for 82° countersink applications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
