Professional Applications & Engineering Value
These No. 8 Phillips pan head tapping screws deliver exceptional performance in sheet metal fastening applications across industrial and construction sectors. The black corrosion-resistant coated steel construction provides reliable protection against environmental factors, while the thread forming design creates strong, permanent threads in ductile materials without chip removal. The combination of 0.164" thread diameter and 15 TPI ensures optimal thread engagement and pull-out resistance. The flanged pan head design eliminates the need for separate washers, streamlining assembly processes in HVAC systems, electrical enclosures, and metal fabrication projects where vibration resistance and long-term durability are critical.
Specification Summary & Compliance
These tapping screws feature precision Class 2A thread tolerances with A/AB thread type specifications. The 1-1/2" length and fully threaded design provide consistent fastening performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in various industrial applications. The screws are engineered for use with No. 29 drill bits (0.136" diameter) and are optimized for sheet metal applications up to 0.025" maximum drilling thickness.
