Professional Applications & Engineering Value

These M5.5 tapping screws deliver exceptional engineering value in sheet metal assembly applications where corrosion resistance and thread integrity are critical. The 18-8 stainless steel composition provides outstanding protection against rust and chemical exposure, making these thread forming screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The coarse thread spacing combined with the pointed tip design enables quick starts and reduces installation torque requirements, while the fully threaded configuration ensures maximum pull-out strength across the entire engagement length. The Phillips pan head offers both aesthetic appeal and practical functionality, sitting flush against surfaces while the No. 3 drive size provides sufficient torque transmission for production environments.

Specification Summary & Compliance

This metric tapping screw features precise M5.5 thread size with 38mm length, manufactured to DIN 7981 standards for dimensional accuracy and performance consistency. The right-hand thread configuration with coarse thread spacing ensures optimal engagement in sheet metal applications. The thread forming tapping method (Type C) creates strong, load-bearing threads without generating chips. Compliance includes meeting standard industrial specifications for dimensional tolerances and material composition, with 18-8 stainless steel providing inherent corrosion resistance suitable for various industrial environments.
