Professional Applications & Engineering Value

This 7/16"-14 UNC hex head screw is engineered to address critical challenges in heavy machinery, structural fabrication, and marine equipment where corrosion resistance and high tensile strength are paramount. The 18-8 stainless steel material prevents rust and degradation in humid or chemical-exposed environments, extending service life and reducing maintenance costs. Its coarse thread spacing and fully threaded design ensure rapid installation and superior holding power in wood, metal, and composite materials, making it a go-to fastener for construction, transportation, and industrial assembly lines. The external hex drive with a substantial head profile allows for secure tool engagement, preventing stripping under high torque conditions commonly encountered in heavy-duty applications.

Specification Summary & Compliance

This hex head screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy and interchangeability. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for use in regulated markets. The specified thread diameter of 0.4375" and 5 1/2" length provide precise engineering tolerances for reliable performance in demanding industrial applications.
