S-90033A150 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating, extending service life in demanding industrial environments.
• Superior thread-forming capability with A/AB type design, creating strong, permanent threads in sheet metal without pre-tapping.
• Maximum material engagement through fully threaded shanks, ensuring exceptional holding power and vibration resistance.
• Streamlined flush installation with standard 82° flat head profile, providing a smooth surface finish and reduced snagging risk.
• Optimized driving efficiency with No. 2 Phillips drive, enabling secure tool engagement and reduced cam-out during installation.
• Precision compatibility with No. 32 drill bits (0.116" diameter), ensuring accurate pilot holes for reliable fastening in 0.025" maximum thickness materials.
• Regulatory confidence with full RoHS 3 and REACH compliance, meeting international environmental and safety standards for industrial use.

Professional Applications & Engineering Value

These black-oxide steel tapping screws are engineered specifically for sheet metal applications where reliability and durability are critical. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger thread engagement than cutting alternatives. The fully threaded design distributes clamping force evenly along the entire fastener length, preventing loosening under vibration – a common challenge in automotive, HVAC, and electronic enclosure assemblies. The flat head profile with standard 82° countersink angle ensures flush mounting without protruding edges, maintaining both aesthetic appeal and safety in finished products. Combined with right-hand threading and No. 2 Phillips drive, these screws deliver consistent performance in high-volume production environments.

Specification Summary & Compliance

This No. 6 x 1/2" Phillips flat head tapping screw features a 0.138" thread diameter with 18 threads per inch, manufactured to standard inch system specifications. The thread forming (A/AB type) design meets industry standards for sheet metal fastening applications, requiring No. 32 drill bits (0.116" diameter) for proper installation. All products are manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and substance restriction requirements for industrial components.
