Professional Applications & Engineering Value

This SAE Grade 2 steel elevator bolt delivers critical performance where reliable fastening meets industrial demands. The fully threaded UNC coarse thread design ensures maximum grip length and superior load distribution across connected materials, while the zinc plating provides essential corrosion protection in humid or chemically aggressive environments. The flat head with wide profile prevents countersinking and maintains surface integrity, making it ideal for elevator systems, conveyor belts, and material handling equipment where vibration resistance and long-term stability are paramount. With its 70,000 psi tensile strength and included matching nut, this fastener solves common industrial challenges of component separation, material fatigue, and maintenance frequency.

Specification Summary & Compliance

This elevator bolt maintains Unified Standard Class 2A thread fit with 5/16"-18 UNC coarse threading and right-hand direction. Manufactured from SAE Grade 2 steel with Rockwell B80 hardness, it delivers consistent dimensional accuracy across all specifications. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) standards, ensuring environmental responsibility and workplace safety.
