S-90197A645 Length 3/4" 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 driving efficiency through the external hex/slotted drive style, allowing for quick installation with standard tools
• Reliable thread-forming capability that creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time
• Secure flange design provides a wider bearing surface, distributing load evenly and preventing pull-through in thin materials
• Optimized for 0.05" maximum drilling thickness, making these screws ideal for precise sheet metal applications with minimal material waste
• Full threading and pointed tip ensure easy starting and consistent grip along the entire length, improving joint integrity
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets global industry standards for hazardous substances

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws are engineered to address common challenges in sheet metal assembly, such as material stripping and corrosion. The thread-forming needle point and fully threaded design eliminate the need for separate tapping operations, reducing labor costs and speeding up production lines. With a 0.19" thread diameter and 12 threads per inch, they deliver high pull-out strength and vibration resistance in HVAC, automotive, and electronics enclosures. The zinc-plated finish enhances durability against moisture and chemicals, while the hex head with flange ensures secure fastening without sinking into softer metals. Ideal for use with a No. 21 drill bit (0.159" diameter), these screws simplify hole preparation and minimize errors in high-volume industrial settings.

Specification Summary & Compliance

These screws feature precise inch system measurements, including a 3/4" length and Class 2A thread tolerances for consistent fit. The thread-forming tapping method adheres to industry standards for sheet metal fasteners, ensuring reliable performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms they are free from restricted substances, supporting sustainable manufacturing practices.
