Professional Applications & Engineering Value

These black-oxide steel tapping screws are engineered specifically for sheet metal applications where durability and corrosion resistance are critical. The thread-forming A/AB tapping screw design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, reliable threads in materials up to 0.025" thick. The Phillips flat head configuration ensures secure driving and flush mounting, while the standard 82° countersink angle matches common sheet metal countersink specifications. The combination of fully threaded design and right-hand threading provides excellent pull-out resistance, making these screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where vibration resistance and long-term reliability are essential.

Specification Summary & Compliance

These No. 6-18 x 1" tapping screws feature precision Class 2A thread tolerances with a 0.138" thread diameter and 18 threads per inch. The standard flat head profile with 0.262" head diameter and 0.083" head height ensures proper seating in prepared holes. Manufactured to meet A/AB tapping screw standards for thread-forming applications, these screws require a No. 32 drill bit (0.116" diameter) for proper installation. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, ensuring environmental responsibility and regulatory adherence for global industrial applications.
