Professional Applications & Engineering Value
These Grade 5 hex head screws deliver critical performance advantages in heavy-duty assembly applications where vibration resistance and structural integrity are paramount. The combination of 7/16"-14 UNC coarse threading and Class 2A thread fit provides excellent engagement in both metallic and non-metallic materials, reducing stripping and cross-threading risks during installation. The zinc plated finish offers substantial protection against corrosion in industrial environments, while the external hex drive accommodates high torque requirements without slippage. Engineered to meet rigorous ASME B18.2.1 specifications, these fully threaded fasteners are ideal for construction equipment, machinery frames, structural connections, and other applications demanding 120,000 psi tensile strength and reliable long-term performance.
Specification Summary & Compliance
This 7/16"-14 UNC hex head screw features precise Class 2A thread tolerances and complies with ASME B18.2.1 and SAE J429 Grade 5 manufacturing specifications. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations, ensuring environmental responsibility. With fully threaded design, right-hand thread direction, and standardized external hex drive, this screw maintains dimensional accuracy across production batches for consistent performance in industrial applications.
