S-90055A197 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
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping in sheet metal
• Secure flush mounting with standard flat head profile and 82° countersink angle for smooth, professional finishes
• Reliable drive engagement with Phillips No. 2 drive style, preventing cam-out and ensuring consistent torque application
• Full-length gripping power with completely threaded shank, maximizing holding strength across the entire fastener length
• Environmental compliance assurance meeting RoHS 3 standards for safe, sustainable manufacturing practices
• Optimized for sheet metal applications with precise No. 8-18 thread specifications and recommended No. 29 drill bit compatibility

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming Type B design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration-induced loosening. The Phillips flat head configuration with 82° countersink provides clean, flush finishes in metal enclosures, electrical boxes, and HVAC components. The fully threaded construction ensures maximum pull-out resistance across the entire engagement length, making these industrial fasteners ideal for applications where structural integrity and long-term reliability are critical. The combination of corrosion-resistant zinc plating and RoHS 3 compliance makes them suitable for both indoor and protected outdoor environments while meeting modern environmental standards.

Specification Summary & Compliance

This No. 8-18 x 3/4" tapping screw features precise inch system measurements with 0.164" thread diameter and 18 threads per inch following standard thread forming specifications. The fastener maintains proper Class 2A thread tolerances for reliable engagement and is manufactured to meet Type B thread forming standards for sheet metal applications. Compliance with RoHS 3 (2015/863/EU) ensures environmental safety, while the specified No. 29 drill bit (0.136" diameter) and 82° countersink angle provide optimal installation parameters for professional results.
