Professional Applications & Engineering Value
These No. 6-18 sheet metal tapping screws deliver exceptional engineering value in industrial fastening applications where corrosion resistance and secure installation are critical. The 18-8 Stainless Steel material provides excellent protection against rust and chemical exposure, while the thread forming tapping method creates durable, vibration-resistant connections in sheet metal without strip-out issues. The drilled spanner drive offers both security and reliable torque transmission, making these fully threaded screws ideal for HVAC systems, electrical enclosures, and metal fabrication where tamper resistance and long-term reliability are essential. The combination of 0.138" thread diameter and 18 TPI ensures optimal holding power in thin-gauge materials.
Specification Summary & Compliance
This No. 6-18 x 1/2" tapping screw features precision right-hand threads with standard inch system tolerances, pan head style with 0.27" head diameter, and requires No. 32 drill bit (0.116" diameter) for proper installation. Manufactured to Type A/AB tapping screw standards with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications.
