Professional Applications & Engineering Value

These No. 8 x 3/4" Phillips flat head tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The Black-Oxide steel construction provides superior corrosion protection, while the thread forming design eliminates the need for pre-tapped holes, creating stronger threads that won't loosen under stress. The A/AB tapping screw type with 15 threads per inch ensures optimal grip in thin materials, making these industrial screws ideal for HVAC systems, electronic enclosures, and automotive panels where reliability is paramount. The combination of 0.164" thread diameter and fully threaded design provides maximum holding power across the entire fastener length.

Specification Summary & Compliance

These tapping screws feature precise right hand thread configuration with standard thread tolerances for consistent performance. The No. 8 screw size with 3/4" length and 0.312" head diameter ensures proper fitment in designated applications requiring No. 29 drill bit (0.136" diameter) preparation. Manufacturing complies with industry standards for thread forming screws, including full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across various industrial sectors.
