Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 5/16"-18 UNC brass rounded head screws deliver exceptional performance where corrosion resistance and mechanical reliability are critical. The Class 3A thread fit ensures precise engagement in machinery, electrical enclosures, and marine equipment, preventing loosening under vibration. The hex drive compatibility with 3/16" tools allows for high-torque installation without stripping, while the fully threaded design maximizes pull-out strength in soft materials and thin-section assemblies. The combination of brass construction and coarse threading makes these fasteners ideal for repeated disassembly in maintenance-heavy environments, providing long-term durability without galling or seizure issues common in stainless alternatives.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 specifications with Class 3A thread tolerances for superior fit and function. These fully threaded 5/16"-18 UNC screws feature coarse thread spacing and right-hand threading direction. Compliance verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The mechanical properties include Rockwell B55 hardness and 50,000 psi tensile strength for reliable performance in demanding applications.
