• Regulatory compliance assurance meeting REACH and RoHS 3 standards for safe use in regulated industrial settings.

Professional Applications & Engineering Value

This SAE Grade 5 elevator bolt delivers critical engineering solutions for industrial machinery and elevator systems where vibration resistance and structural integrity are paramount. The square neck design eliminates rotation during installation, while the fully threaded 5/16"-18 UNC coarse thread provides maximum grip length and load distribution. The zinc yellow-chromate plating creates a protective barrier against corrosion in harsh environments, significantly extending maintenance intervals. With 120,000 psi tensile strength and Rockwell C25 hardness, these bolts maintain clamping force under dynamic loads, preventing loosening in elevator guide rails, conveyor systems, and heavy equipment assemblies. The combination of flat head profile and integrated nut offers flush mounting and secure fastening for professional industrial applications.
