S-91675A353 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction for extended service life in demanding industrial environments
• Enhanced installation efficiency through external hex drive design allowing high-torque application with standard tools
• Eliminates need for separate washers with integrated flange design that distributes load and prevents pull-through
• Strong, permanent threads created by thread forming technology that displaces material rather than cutting it
• Full-length threading provides maximum engagement and holding power throughout the entire fastener length
• Optimized for sheet metal applications with pointed tip and specific drill bit compatibility for precise, secure installations
• Compliance with environmental regulations including RoHS 3 and REACH for global manufacturing acceptance

Professional Applications & Engineering Value

These 410 Stainless Steel flanged hex head tapping screws deliver exceptional performance in sheet metal fabrication and assembly applications. The thread forming design creates stronger, more reliable threads by cold-forming material rather than removing it, eliminating chip removal issues in automated production. The external hex drive accommodates high torque applications while the integrated flange provides superior clamping force distribution, reducing stress concentrations and preventing material deformation. Fully compatible with No. 21 drill bits, these screws ensure precise fitment in 0.025" maximum thickness materials, making them ideal for HVAC systems, electronic enclosures, and automotive panels where vibration resistance and environmental durability are critical.
