Professional Applications & Engineering Value
These Type A/AB thread forming screws are specifically engineered for demanding sheet metal applications where reliability and corrosion resistance are critical. The 18-8 stainless steel construction provides exceptional durability against oxidation and chemical exposure, making these tapping screws ideal for HVAC systems, electrical enclosures, and automotive assemblies. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The combination of right-hand threading and pointed tip ensures quick starts and smooth penetration through sheet metal up to 0.025" thickness, while the Phillips pan head delivers excellent drive stability and a low-profile finish.
Specification Summary & Compliance
These No. 6-18 tapping screws feature standard inch measurements with 18 threads per inch and a thread diameter of 0.138". The Type A/AB thread forming design conforms to industry standards for sheet metal fastening applications. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The screws are designed for use with No. 32 drill bits (0.116" diameter) and provide reliable performance in various industrial settings.
