Professional Applications & Engineering Value
This SAE Grade 5 elevator bolt delivers exceptional engineering value for industrial machinery and material handling systems. The steel construction combined with zinc yellow-chromate plating provides robust protection against corrosion in demanding environments like warehouses and manufacturing facilities. The square neck design fundamentally solves the common problem of bolt rotation during installation, ensuring secure positioning in elevator shoes, conveyor frames, and other equipment where anti-rotation is critical. The fully threaded UNC coarse thread configuration enables rapid assembly while maintaining strong clamping force, making these industrial bolts ideal for high-vibration applications where fastener integrity is paramount. The combination of medium strength rating and precise Class 2A thread fit ensures reliable performance in repetitive assembly operations.
Specification Summary & Compliance
This elevator bolt features Unified Standard Class 2A thread fit with 1/4"-20 UNC coarse threading and right-hand thread direction. Manufacturing complies with SAE Grade 5 standards, delivering 120,000 psi tensile strength and Rockwell C25 hardness. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring suitability for various industrial applications without restricted substance concerns.
