S-90086A626 10-32 x 5/8" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments
• Effortless installation through thread-cutting design that eliminates the need for pre-tapped holes in materials like aluminum and cast iron
• Maximum torque transfer with No. 2 Phillips drive, reducing cam-out and improving installation efficiency
• Flush surface finish achieved with 82° countersink angle and standard flat head profile for clean, professional applications
• Exceptional holding power in sheet metal and non-ferrous metals through UNF fine thread configuration
• Full-thread engagement along the entire 5/8" length for superior load distribution and vibration resistance
• Industry compliance assurance meeting ASME B18.6.3 specifications and RoHS 3 environmental standards

Professional Applications & Engineering Value

These 10-32 thread cutting screws deliver exceptional engineering value by solving critical fastening challenges in aluminum, brass, cast iron, and sheet metal applications. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The UNF fine thread configuration ensures superior grip in thin materials and soft metals, preventing stripping and maintaining joint integrity. The thread-cutting design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. With precise 82° countersink angle and No. 2 Phillips drive, these tapping screws provide reliable, flush-mount fastening solutions for automotive, HVAC, and manufacturing applications where vibration resistance and long-term performance are critical.

Specification Summary & Compliance

These thread cutting screws feature precise 10-32 UNF fine threads with standard Class 2A tolerance for consistent performance. The manufacturing process strictly adheres to ASME B18.6.3 specifications (SAE J933) ensuring dimensional accuracy and mechanical properties. Environmental compliance is maintained through RoHS 3 (2015/863/EU) certification, guaranteeing the absence of restricted hazardous substances. The zinc-plated surface treatment provides corrosion protection while the 0.362" head diameter and 5/8" length deliver optimal fastening geometry for the specified drill bit size of No. 16 (0.177" diameter).
