Professional Applications & Engineering Value

This Type A/AB thread forming tapping screw delivers exceptional value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor conditions. The thread forming design eliminates the need for tapping operations by cold-forming mating threads directly into the material, resulting in zero chip generation and superior thread integrity. This feature is particularly valuable in electrical enclosures, HVAC systems, and automotive components where loose metal particles could cause damage. The combination of No. 6 screw size with 18 threads per inch and 0.138" thread diameter creates optimal pull-out strength while the pan head style offers a low-profile finish with excellent clamp load distribution.

Specification Summary & Compliance

This tapping screw features precision right-hand threads with standard Class 2A thread tolerances, ensuring consistent performance across production runs. The fully threaded construction provides maximum engagement throughout the 3/4" length, while the pointed tip facilitates easy insertion. Manufacturing complies with industry standards for Type A/AB thread forming screws, and the product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for use in regulated industries and international markets.
