Professional Applications & Engineering Value
These thread forming 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 A/AB thread forming design creates stronger threads by displacing material rather than removing it, eliminating chip-related contamination in sensitive assemblies. The Phillips oval head combines aesthetic appeal with functional benefits, seating flush to prevent snagging while the 82° countersink ensures proper alignment. Engineered for industrial-grade reliability, these screws maintain integrity in HVAC systems, electronic enclosures, and metal fabrication where consistent clamping force and long-term durability are paramount.
Specification Summary & Compliance
Precision-manufactured to exacting standards with 0.164" thread diameter and 15 threads per inch for optimal engagement in sheet metal applications. Features fully threaded design with standard Class 2A thread tolerances and right-hand threading for consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. Designed specifically for 0.025" maximum drilling thickness with recommended No. 29 drill bit preparation (0.136" diameter) for proper thread formation.
