- Compliance with ASME B18.2.1 ensures consistent quality, dimensional accuracy, and interchangeability for reliable B2B sourcing.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these 9/16"-12 UNC hex head screws in 316 Stainless Steel address common challenges like corrosion, vibration loosening, and high-stress conditions. The coarse thread design and Class 2A thread fit provide secure fastening in soft or coarse materials, minimizing thread galling and ensuring repeatable performance. With a partially threaded shank, they offer optimal grip range for assemblies requiring precise unthreaded engagement, making them ideal for machinery, structural frameworks, and marine equipment where corrosion-resistant fasteners are critical. The external hex drive simplifies maintenance and disassembly, reducing downtime in production environments.
Specification Summary & Compliance
This hex head screw features a 9/16"-12 UNC coarse thread with Class 2A tolerance for consistent fit and performance. It meets ASME B18.2.1 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for global industrial use.
