Key Features & Benefits at a Glance
- Superior Thread Cutting Performance – Self-tapping design with UNC coarse threads ensures quick, secure installation in aluminum, brass, cast iron, and sheet metal without pre-threading.
- Enhanced Corrosion Resistance – Zinc-plated steel construction provides reliable protection against rust and wear in demanding industrial environments.
- High-Torque Fastening Capability – External hex drive and flanged head design allow for easy installation with standard tools and distribute clamping force evenly.
- Full-Length Threading for Maximum Grip – Fully threaded shank increases holding power and vibration resistance across the entire fastener length.
- Industry-Standard Compliance – Manufactured to ASME B18.6.3 specifications, ensuring dimensional accuracy, interchangeability, and consistent performance.
- Environmental and Safety Compliance – RoHS 3 compliant for safe use in regulated applications, free from hazardous substances.
- Optimized for Common Materials – Designed specifically for use with No. 31 drill bit (0.12" diameter), simplifying hole preparation in metals.
Professional Applications & Engineering Value
These 6-32 UNC thread cutting tapping screws are engineered to address common challenges in metal assembly, such as stripping, loosening under vibration, and corrosion. The zinc-plated steel material offers durability, while the coarse thread and thread cutting design enable strong, permanent threads in softer metals like aluminum and sheet metal, as well as tougher substrates like cast iron and brass. The flanged head eliminates the need for separate washers, speeding up assembly and reducing part count. Ideal for HVAC, automotive, and machinery applications, these screws deliver reliable, long-term fastening with minimal maintenance.
Specification Summary & Compliance
This No. 6 screw features a 1/2" length, fully threaded shank, and UNC coarse thread with standard Class 2A tolerances for precise fit. It complies with ASME B18.6.3 manufacturing standards and is RoHS 3 (2015/863/EU) compliant, ensuring environmental safety and industrial reliability.
