Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 5/16"-18 UNC hex head screw in 316 stainless steel addresses critical challenges in marine, chemical processing, and outdoor infrastructure applications. The coarse thread configuration ensures rapid installation in thick materials while maintaining vibration resistance, significantly reducing assembly time in production lines. With partial threading design, the fastener provides concentrated clamping force where needed while allowing for material expansion/contraction. The external hex drive delivers maximum torque transmission without cam-out issues, making it ideal for high-stress connections in structural frameworks, machinery assembly, and equipment manufacturing where corrosion resistance and mechanical reliability are paramount.
Specification Summary & Compliance
This hex head screw maintains precision Class 2A thread tolerances per UNC standards with 0.3125" thread diameter and 1-1/8" minimum thread length. Manufacturing complies with ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, ensuring suitability for regulated industries and international projects.
