• Precision-engineered dimensions (0.164" thread diameter, 18 TPI) guarantee consistent performance and interchangeability in sheet metal assemblies

Professional Applications & Engineering Value

These Type B thread forming screws are specifically engineered for sheet metal applications where reliable fastening and corrosion resistance are critical. The 18-8 stainless steel composition provides exceptional durability against moisture, chemicals, and temperature variations, making these tapping screws ideal for HVAC systems, electrical enclosures, and industrial equipment manufacturing. The thread forming technology eliminates the need for separate tapping operations, creating strong, strip-resistant threads that maintain integrity under vibration and load. The Phillips pan head design with No. 2 drive ensures compatibility with standard industrial drivers while providing a clean, flush installation profile. These fully threaded screws deliver maximum engagement in materials ranging from thin gauge sheet metal to composite panels, solving common challenges of thread stripping and loosening in dynamic industrial environments.

Specification Summary & Compliance

This No. 8-18 x 1-1/4" tapping screw features precision thread forming with a 0.164" thread diameter and 18 threads per inch, designed specifically for use with No. 29 drill bits (0.136" diameter). The Type B thread form and right-hand threading comply with industry standards for sheet metal fastening applications. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for global industrial use.
