S-90190A089 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments.
• Excellent thread-forming capability with A/AB type design creates secure, high-retention threads in sheet metal without pre-tapping.
• Optimized for thin materials with a maximum drilling thickness of 0.025", preventing material damage and ensuring reliable fastening.
• Efficient installation with Phillips No. 1 drive and fully threaded pointed tip for quick, straightforward driving and alignment.
• Secure and stable fastening provided by the pan head style, offering a larger bearing surface for improved clamp load distribution.
• Precision fit and reliable performance with a 0.086" thread diameter and 32 TPI, ensuring consistent engagement in sheet metal applications.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and international supply chains.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication and assembly. The thread-forming (tapping) design eliminates the need for separate tapping operations, reducing assembly time and labor costs while minimizing the risk of cross-threading. The zinc plating provides a durable barrier against corrosion, essential for components exposed to varying environmental conditions in HVAC, electronics enclosures, and automotive panels. The combination of a Phillips drive and pan head ensures efficient torque transfer and a low-profile finish, making these A/AB type screws ideal for high-volume production lines where speed, reliability, and consistent clamp force are critical to structural integrity.

Specification Summary & Compliance

This product features a 0.086" thread diameter with 32 threads per inch and a 3/4" length, designed as a thread-forming tapping screw for use in sheet metal. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to strict environmental and safety standards for industrial components.
