S-90184A496 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
• Superior thread-forming capability creates precise, secure threads in sheet metal without pre-tapping, reducing installation time
• Full threading along the 2-1/2" length provides maximum grip and holding power throughout the entire fastener engagement
• Phillips drive with No. 3 size ensures common tool compatibility and prevents cam-out during installation
• Pan head design with standard profile offers a low-profile finish while providing adequate bearing surface
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets international industrial standards
• Optimized for 0.1875" drill holes in sheet metal up to 0.025" thickness, ensuring precise fit and reduced material stress

Professional Applications & Engineering Value

These 316 stainless steel tapping screws deliver exceptional performance in sheet metal fabrication and industrial assembly where corrosion resistance is critical. The thread forming design eliminates the need for separate tapping operations, significantly reducing labor costs and installation time in high-volume production environments. With their fully threaded shank and 11 threads per inch configuration, they provide superior pull-out resistance and vibration resistance in thin-gauge materials. The Phillips drive system ensures widespread tool compatibility across manufacturing facilities, while the pan head style offers a clean, professional appearance without sacrificing clamping force. These fasteners are particularly valuable in marine, chemical processing, and food processing equipment where moisture and chemical exposure would degrade inferior materials.

Specification Summary & Compliance

This No. 12 tapping screw features a 0.216" thread diameter with 11 threads per inch in right-hand direction, conforming to Class 2A thread tolerances for reliable engagement. The A/AB thread forming type ensures consistent performance in sheet metal applications up to 0.025" thickness when used with recommended 3/16" drill bits. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability for global markets.
