S-90065A028 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Excellent thread forming capability with AB type tapping design, creating strong, permanent threads in sheet metal
• Optimized for No. 55 drill bits (0.052" diameter) with 82° countersink angle for flush, professional installations
• High thread density (48 TPI) provides superior holding power and vibration resistance in thin materials
• Fully threaded design with pointed tip ensures maximum engagement and easier starting in pre-drilled holes
• Phillips drive compatibility with No. 0 size offers widespread tool accessibility and efficient installation
• Environmental compliance with RoHS 3 standards, meeting global regulatory requirements for industrial use

Professional Applications & Engineering Value

These No. 0 Phillips flat head tapping screws deliver exceptional performance in sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides outstanding corrosion resistance, while the thread forming design eliminates the need for separate tapping operations, reducing assembly time and costs. The fully threaded configuration with 48 threads per inch ensures maximum surface contact and superior pull-out strength in materials up to 0.025" thickness. The standard flat head profile with 82° countersink angle sits flush with surfaces, preventing snagging and maintaining aerodynamic profiles in metal enclosures, electronic chassis, and HVAC components.

Specification Summary & Compliance

These precision thread forming screws feature a 0.06" thread diameter with 48 TPI right-hand threading, manufactured to AB type standards for optimal performance in sheet metal. The screws are designed for use with No. 55 drill bits (0.052" diameter) and comply with RoHS 3 (2015/863/EU) environmental regulations. The flat head design incorporates standard dimensions with 0.112" head diameter and 0.035" head height, ensuring consistent performance across industrial applications requiring reliable tapping screw solutions.
