S-90054A251 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments.
• Enhanced fastening stability from the flanged hex head design, which distributes load evenly and prevents pull-through in sheet metal.
• Efficient, secure installation using thread forming technology that eliminates the need for pre-tapping, saving time and reducing assembly costs.
• High grip strength with a fully threaded No. 10-12 design and 1-1/2" length, ensuring maximum holding power in metal applications.
• Versatile external hex/slotted drive allows for easy installation with common tools, improving workflow efficiency.
• Reliable performance in sheet metal up to 0.025" thickness, backed by precise thread dimensions and pointed tip for quick starting.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe, sustainable use in global supply chains.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fastening, such as material fatigue and loosening under vibration. The thread forming method creates strong, permanent threads in the base material without chips, reducing the risk of weak points. With a flanged hex head and fully threaded No. 10-12 design, they provide uniform clamping force and resist back-out, making them ideal for HVAC systems, automotive panels, and industrial enclosures. The combination of external hex drive and precise dimensions ensures quick, tool-friendly installation, minimizing labor time while meeting rigorous industrial safety standards.

Specification Summary & Compliance

This screw features a No. 10-12 thread with a diameter of 0.19" and approximately 12 threads per inch, adhering to standard inch measurements for consistent fit. The thread forming tapping method and pointed tip facilitate easy insertion in sheet metal, with a maximum drilling thickness of 0.025" using a No. 21 drill bit (0.159" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial applications.
