- Right-hand thread direction ensures compatibility with standard installation procedures and equipment
Professional Applications & Engineering Value
These brass hex head screws deliver critical performance advantages where corrosion resistance and electrical conductivity are paramount. The UNC coarse thread configuration prevents binding in soft materials and allows rapid installation in production environments, while the fully threaded design ensures consistent clamping force across the entire engagement length. Engineered with Rockwell B55 hardness and 50,000 psi tensile strength, these industrial fasteners maintain structural integrity in vibration-prone applications such as electrical enclosures, marine equipment, and plumbing systems. The external hex drive provides superior torque transmission compared to internal drive types, reducing tool slippage and installation damage in high-volume assembly operations.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 2A thread fit tolerance for consistent mating with standard nuts and threaded holes. The 5/16"-18 UNC coarse thread pattern follows established industrial standards while the 1" length provides versatile application coverage. Compliance with ASME B18.2.1 ensures dimensional accuracy and mechanical properties, while RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications guarantee environmental responsibility and workplace safety compliance.
