Key Features & Benefits at a Glance
- Self-tapping efficiency: Cuts precise threads in materials like aluminum and cast iron without pre-tapping, reducing installation time and labor costs.
- Enhanced corrosion resistance: Black-oxide steel finish provides reliable protection against rust in industrial environments, extending service life.
- Secure fastening in coarse threads: UNC coarse thread design ensures strong grip and vibration resistance in sheet metal and soft metals.
- Optimized drive engagement: Phillips No. 2 drive offers controlled torque application, minimizing cam-out and tool slippage during assembly.
- Full-threaded design: Maximizes holding power along the entire 1/2" length for consistent load distribution in demanding applications.
- Standardized compatibility: Meets ASME B18.6.3 specifications for dimensional accuracy, ensuring interchangeability and reliability.
- Environmentally compliant: RoHS 3 adherence guarantees safe use in regulated industries without hazardous substances.
Professional Applications & Engineering Value
These 6-32 UNC thread cutting screws are engineered to address common challenges in metal assembly, such as stripping and loose fittings. The thread cutting capability (Type F) allows direct installation into aluminum, brass, cast iron, and sheet metal without pre-drilled threads, eliminating secondary operations. The black-oxide steel construction combats corrosion in humid or outdoor settings, while the flat head with 82° countersink sits flush for aerodynamic or safety-critical surfaces. With a coarse UNC thread and Phillips No. 2 drive, they deliver high torque resistance and ease of use in automated or manual fastening, making them ideal for HVAC, automotive, and machinery sectors where durability and precision are paramount.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a 6-32 size and coarse spacing, ensuring compatibility with standard nuts and holes. Dimensions include a 0.262" head diameter, 1/2" length, and fully threaded shank per ASME B18.6.3 specifications. It is designed for use with a No. 31 drill bit (0.12" diameter) and meets RoHS 3 (2015/863/EU) compliance for environmental safety, supporting sustainable manufacturing practices.
