- Precision Thread Fit – Unified Standard Class 2A thread fit guarantees consistent, reliable engagement with mating components.
Professional Applications & Engineering Value
This SAE Grade 2 steel elevator bolt is engineered to address common industrial challenges such as vibration loosening and material fatigue. The fully threaded design and coarse UNC thread provide excellent grip in soft or composite materials, making it ideal for elevator systems, conveyor belts, and machinery assembly. The wide flat head prevents pull-through in sheet metal or wood, while the 70,000 psi tensile strength ensures integrity under dynamic loads. Its right-hand thread and inch system measurements offer compatibility with standard North American equipment, streamlining maintenance and reducing downtime in heavy-duty applications.
Specification Summary & Compliance
This elevator bolt adheres to Unified Standard Class 2A thread fit and UNC coarse thread specifications (5/16"-18). It is manufactured from SAE Grade 2 steel with a hardness of Rockwell B80 and meets REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliance standards, ensuring environmental safety and regulatory alignment for industrial use.
