Professional Applications & Engineering Value
This heavy-duty hex head screw delivers exceptional engineering value in demanding applications where corrosion resistance and structural integrity are paramount. The 18-8 Stainless Steel composition provides superior protection against rust and chemical degradation, making it ideal for marine equipment, food processing machinery, and outdoor structural assemblies. The 1 1/8"-7 UNC coarse thread spacing ensures rapid installation and superior holding power in soft materials and thick sections. The partially threaded design concentrates clamping force precisely where needed, preventing joint loosening under vibration while the external hex drive accommodates high-torque installation with standard tools. These industrial hex screws solve critical challenges in construction, heavy machinery, and infrastructure projects where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 2A thread fit tolerance for consistent performance. Features 1 1/8"-7 UNC coarse threads with right-hand thread direction and minimum 2 1/2" thread length. The partially threaded configuration provides optimal stress distribution. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
