S-90055A322 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
• Effortless installation through thread forming design that creates strong, permanent threads without pre-tapping in sheet metal
• Secure flush mounting with 82° countersink angle and flat head profile for smooth, professional finishes
• Optimized driving efficiency with Phillips No. 2 drive that prevents cam-out and ensures consistent torque application
• Maximum holding power through fully threaded design that distributes load evenly across the entire fastener length
• Precision compatibility with No. 21 drill bits for accurate hole preparation and reduced installation time
• Environmental compliance with RoHS 3 regulations for safe use in regulated industries and applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming Type B design eliminates the need for separate tapping operations by cold-forming precise mating threads directly into the base material, creating superior pull-out strength compared to conventional fasteners. The fully threaded configuration ensures maximum engagement across the entire 3/4" length, while the 82° countersink angle provides clean, flush installations in metal fabrication, HVAC systems, and industrial equipment assembly. The combination of Phillips drive and precise No. 10-16 thread pitch makes these screws ideal for high-volume production environments where speed and reliability are paramount.

Specification Summary & Compliance

This Type B thread forming tapping screw features precision Class 2A thread tolerances with 16 threads per inch and 0.19" thread diameter. The fastener is manufactured to industry standards for sheet metal applications with compatibility for No. 21 drill bits (0.159" diameter). Compliance includes RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and regulatory acceptance for industrial and construction use across global markets.
