Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 150,000 PSI tensile strength, ideal for high-stress industrial assemblies.
- Superior wear and deformation resistance due to Grade 8 steel and Rockwell C33 hardness, extending service life.
- Reliable coarse threading (1-1/2"-6 UNC) ensures quick assembly and secure fastening in tough materials.
- Precision Class 2A thread fit guarantees consistent engagement and reduces cross-threading risks.
- Partially threaded 10" length provides optimal grip range and flexibility for varied joint thicknesses.
- External hex drive with 2-1/4" head width offers high torque application capability and easy installation.
- Compliance with ASME B18.2.1 and SAE J429 ensures adherence to rigorous industrial standards for safety.
Professional Applications & Engineering Value
This Grade 8 hex head screw is engineered to address critical challenges in heavy machinery, construction, and structural applications where vibration and dynamic loads are common. The 1-1/2"-6 UNC coarse thread design minimizes thread stripping in soft or coarse-grained materials, while the partially threaded shank concentrates clamping force precisely where needed. Made from high-strength steel and heat-treated to Rockwell C33 hardness, it resists shear and tensile failures under extreme conditions. The external hex drive allows for high-torque tightening with standard tools, making it a reliable choice for industrial fastening in automotive, agricultural, and manufacturing sectors that demand durability and consistent performance.
Specification Summary & Compliance
This fastener features a 1-1/2"-6 UNC coarse thread with Class 2A fit for standard tolerance and easy assembly. It meets ASME B18.2.1 and SAE J429 specifications, ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally conscious and safe industrial use.
