Key Features & Benefits at a Glance
- Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Superior material penetration through thread-cutting Type F design, ensuring reliable, self-tapping fastening in aluminum, brass, cast iron, and sheet metal.
- High-torque installation capability with the external hex drive and hex head, allowing for secure, efficient driving with standard tools.
- Eliminates the need for separate washers thanks to the integrated flange, which provides a larger bearing surface for improved load distribution.
- Optimized for quick assembly with UNC coarse thread spacing and full threading, enabling faster installation and reduced labor time.
- Guaranteed dimensional consistency and performance reliability, meeting the rigorous ASME B18.6.3 standard for quality assurance.
- Safe for regulated applications with RoHS 3 compliance, ensuring environmental and health safety standards are met.
Professional Applications & Engineering Value
This heavy-duty 8-32 tapping screw is engineered to address common challenges in metalworking and assembly, such as stripping and poor thread engagement. Made from zinc-plated steel, it offers excellent durability against corrosion, while the Type F thread-cutting tip and UNC coarse threads efficiently form mating threads in materials like aluminum, brass, cast iron, and sheet metal without pre-tapped holes. The external hex drive and flanged design ensure maximum torque transfer and stability, reducing the risk of loosening under vibration. Ideal for HVAC, automotive, and machinery applications, this screw simplifies installations, lowers assembly costs, and enhances structural integrity in right-hand threaded fastening systems.
Specification Summary & Compliance
This screw features a No. 8-32 UNC thread with coarse spacing and a 3/4" length, ensuring precise fit in accordance with standard inch measurements. It is designed for use with a No. 26 drill bit (0.147" diameter) and complies with ASME B18.6.3 specifications, guaranteeing dimensional accuracy and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for hazardous substance restrictions.
