Professional Applications & Engineering Value
Engineered for demanding industrial applications, these brass hex head screws address critical challenges in corrosive or electrical environments. The 3/8"-16 UNC coarse thread provides rapid assembly and superior resistance to loosening under vibration, while the external hex drive ensures high torque capability without stripping. The partially threaded design concentrates clamping force precisely where needed, preventing joint distortion. With inherent corrosion resistance from brass material and compliance with ASME B18.2.1, these fasteners deliver long-term reliability in plumbing, electrical enclosures, marine hardware, and machinery where galvanic compatibility and durability are paramount.
Specification Summary & Compliance
This hex head screw features a 3/8"-16 UNC thread with Class 2A tolerance for consistent fit, partial threading up to 1" minimum length, and dimensions per inch system. Manufacturing conforms to ASME B18.2.1 specifications, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use across global industrial sectors.
