Professional Applications & Engineering Value
This 316 stainless steel flanged hex head tapping screw delivers exceptional value in demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for pre-tapped holes, creating strong, permanent threads that won't strip or loosen under vibration. The flanged head distributes clamping force evenly across a wider surface area, preventing material deformation while the external hex drive allows for high-torque installation with standard tools. These sheet metal screws are engineered to maintain their holding power in thin gauge materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and industrial equipment where reliable fastening is critical to operational safety and longevity.
Specification Summary & Compliance
This No. 14 size tapping screw features a 1-1/2" length with 10 TPI fully threaded configuration and pointed tip for optimal performance. Manufactured to precise dimensional standards with Class 2A thread tolerances for consistent fit and function. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications while maintaining the superior corrosion resistance properties of 316 stainless steel.
