Professional Applications & Engineering Value

This elevator bolt is engineered to address critical challenges in material handling and industrial machinery. The steel construction with zinc plating provides robust protection against rust and wear, ideal for elevator systems, conveyor belts, and lifting equipment where moisture and friction are concerns. The square neck design locks securely into surfaces, preventing spin-out during torque application, while the fully threaded UNC coarse thread ensures rapid installation and high pull-out resistance. With a Rockwell B80 hardness and SAE Grade 2 rating, it delivers consistent performance in low-strength applications, reducing downtime and maintenance costs. This bolt is a reliable choice for OEMs and maintenance teams seeking efficiency and compliance in industrial fastening solutions.

Specification Summary & Compliance

This elevator bolt adheres to Unified Standard Class 2A thread fit and UNC coarse threading (1/4"-20) for precise dimensional accuracy. It meets SAE Grade 2 standards with a tensile strength of 70,000 PSI and hardness of Rockwell B80. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
