S-90055A312 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Enhanced holding power through thread forming Type B design, creating strong, permanent threads in sheet metal without pre-tapping.
• Optimal flush installation with undercut flat head and 82° countersink angle, providing a clean finish and preventing surface protrusion.
• Efficient driving and reduced cam-out with Phillips No. 2 drive, allowing for quick installation and minimizing tool slippage.
• Maximum thread engagement with fully threaded 1/2" length and 16 TPI, delivering consistent clamping force across the entire fastener.
• Precision compatibility with No. 21 drill bit (0.159" diameter), ensuring proper hole sizing for secure thread formation in sheet metal applications.
• Environmental compliance assurance meeting RoHS 3 standards, making these screws suitable for regulated industries and global supply chains.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and corrosion resistance are critical. The thread forming Type B technology eliminates the need for pre-tapped holes, reducing installation time and preventing thread stripping in thin materials. The undercut flat head design with 82° countersink angle ensures flush mounting while maximizing surface contact area, distributing clamping force evenly to prevent material deformation. The Phillips drive system provides secure tool engagement during high-volume assembly operations, making these industrial tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and machinery fabrication where vibration resistance and long-term performance are essential.
