S-90065A127 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Excellent holding power in sheet metal due to thread forming design, which creates strong, secure threads without pre-tapping.
• Flush, professional finish with a standard flat head and 82° countersink angle, allowing the screw to sit perfectly flush with the material surface.
• Efficient installation using a No. 2 Phillips drive, providing a secure grip and reducing the risk of cam-out during high-torque applications.
• Full-length threading for maximum grip along the entire shank, enhancing pull-out resistance in thin sheet metal up to 0.025" thickness.
• Precise compatibility with a No. 36 drill bit (0.1065" diameter), ensuring accurate pilot holes and reducing material stress during installation.
• Environmental compliance with RoHS 3 and REACH standards, making these screws safe for use in regulated industries and global markets.

Professional Applications & Engineering Value

These No. 5 x 3/4" 18-8 stainless steel Phillips flat head tapping screws are engineered specifically for demanding sheet metal applications, where material thinness and joint integrity are critical. The thread forming technology displaces material to create strong, permanent threads without generating chips, eliminating the risk of loose metal debris in sensitive assemblies. Made from corrosion-resistant 18-8 stainless steel, these screws withstand exposure to moisture, chemicals, and outdoor elements, making them ideal for HVAC systems, electronic enclosures, and automotive panels. The flat head design with an 82° countersink ensures a smooth, flush finish that prevents snagging and improves aesthetic appeal. With a No. 2 Phillips drive, installers benefit from quick, secure fastening that minimizes tool slippage and reduces assembly time in high-volume production environments.

Specification Summary & Compliance

This tapping screw features a No. 5 size with a 0.125" thread diameter and 20 threads per inch, providing precise engagement in sheet metal. The screw is fully threaded and designed for use with a No. 36 drill bit (0.1065" diameter) for optimal pilot hole preparation. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they are free from hazardous substances and suitable for industrial use worldwide.
