• Enhanced durability and corrosion resistance from high-quality steel construction, extending service life in demanding applications.
• Secure and efficient installation with a high-profile external hex drive, allowing for high torque application without stripping.
• Full compliance with SAE J995 specifications, guaranteeing consistent quality, dimensional accuracy, and interchangeability.
• Environmental and workplace safety assurance through RoHS 3 and REACH compliance, meeting strict regulatory standards.
• Optimized for heavy-duty assemblies with a robust 1 1/8" width and 1" height, providing a larger bearing surface for distributed pressure.

Professional Applications & Engineering Value

This Grade 8 steel hex nut is engineered to address critical challenges in heavy machinery, automotive, and construction sectors, where vibration, high tensile loads, and harsh operating conditions are common. The 3/4"-16 UNF fine thread design offers increased shear strength and better fatigue resistance compared to coarse threads, reducing the risk of thread stripping under repeated stress. The high profile and external hex drive facilitate secure gripping with standard wrenches, enabling precise torque control during assembly. Made from high-strength steel and compliant with SAE J995, this nut ensures reliable performance in bolted joints requiring Class 2B thread fit for tight, consistent engagement. Its RoHS and REACH compliance further supports use in regulated industries, prioritizing both mechanical integrity and environmental responsibility.

Specification Summary & Compliance

This hex nut adheres to SAE J995 standards, with precise Class 2B thread fit for uniform engagement and UNF 3/4"-16 fine threads in a right-hand direction. Manufacturing follows inch system dimensions, including a width of 1 1/8" and height of 1". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets current environmental and safety requirements for industrial fasteners.
