Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments
- Enhanced torque transmission and reduced cam-out thanks to the Torx T15 drive, providing secure fastening and minimizing tool slippage
- Exceptional tensile strength of 60,000 PSI combined with Rockwell B70 hardness for reliable performance under heavy loads
- Precise Class 3A thread fit ensures tight, secure connections with minimal risk of loosening in vibration-prone applications
- Fully threaded design maximizes grip and holding power across the entire length for superior assembly integrity
- Standard 82° countersink angle allows for flush mounting, creating a smooth surface finish and reducing snag hazards
- Compliance with ASME B18.6.3, RoHS 3, and REACH guarantees adherence to industry standards and environmental safety regulations
Professional Applications & Engineering Value
These 8-32 UNC flat head Torx screws are engineered to address critical challenges in industrial assembly, where vibration resistance, corrosion protection, and high tensile strength are paramount. The zinc-plated steel construction provides a durable barrier against moisture and chemicals, extending service life in demanding environments like machinery, automotive, and outdoor equipment. The Torx T15 drive minimizes stripping and allows for higher torque application, ensuring consistent clamping force in high-stress applications. With a coarse UNC thread and Class 3A fit, these screws offer rapid installation and reliable performance in materials where fine threads might fail, reducing assembly time and maintenance costs while meeting rigorous ASME B18.6.3 standards.
Specification Summary & Compliance
This fastener features a 1-1/2" length with fully threaded 8-32 UNC coarse threads and a Class 3A thread fit for precise dimensional accuracy. It complies with ASME B18.6.3 manufacturing specifications and is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets international safety and environmental regulations for industrial use.
