S-90048A252 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• Effortless installation thanks to the Phillips drive and pointed tip, reducing assembly time and tool slippage.
• Strong, secure fastening in sheet metal up to 0.025" thickness, with thread forming design that creates durable, vibration-resistant threads.
• Flush, professional finish achieved with the standard 82° flat head profile, ideal for applications requiring a smooth surface.
• Full-length threading provides maximum grip and holding power along the entire screw length for enhanced joint integrity.
• Compliance with environmental standards including RoHS 3 and REACH, making them suitable for global supply chains and regulated industries.
• Precision compatibility with No. 21 drill bits (0.159" diameter), ensuring accurate pilot holes and reduced risk of material damage.

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are engineered to address common challenges in sheet metal assembly, such as strip-out and weak thread engagement. The zinc-plated steel material offers excellent durability against rust, while the Phillips flat head design allows for a clean, countersunk finish that minimizes protrusion. The thread forming (A/AB type) action displaces material to create strong, permanent threads without chips, reducing the need for tapped holes and speeding up production lines in industrial and construction settings. This results in reliable, vibration-resistant connections that maintain integrity under stress, making them ideal for HVAC, automotive, and machinery enclosures.

Specification Summary & Compliance
