• High tensile strength of 80,000 psi ensures reliable performance under heavy loads and in demanding applications.
• Rockwell B70 hardness provides superior durability and resistance to wear, extending the fastener's service life.
• Coarse UNC thread and Class 2A fit offer easier, faster assembly and reliable engagement in a wide range of materials.
• External hex drive and hex head design allow for high-torque installation with standard tools, simplifying maintenance.
• Partially threaded shank provides an unthreaded section for precise clamping and improved shear strength.
• Compliance with ASME B18.2.1, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility.

Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw is engineered to solve critical challenges in industrial applications where strength and corrosion resistance are paramount. The 18-8 stainless steel construction prevents rust and degradation in outdoor, marine, or chemical-exposed settings, reducing downtime and replacement frequency. Its coarse thread and Class 2A thread fit ensure quick, secure fastening in structural assemblies, machinery, and heavy equipment, minimizing the risk of cross-threading. The partially threaded design concentrates clamping force effectively, making it ideal for securing components that require precise alignment and vibration resistance. As a heavy-duty hex bolt with an external hex drive, it supports high-torque applications, providing reliable performance in construction, manufacturing, and infrastructure projects.

Specification Summary & Compliance

This fastener adheres to Class 2A thread fit tolerances and the UNC coarse thread standard, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with the ASME B18.2.1 specification for hex bolts and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming it is free from hazardous substances and suitable for global industrial use.
