Heavy-Duty Hexagonal Threaded Bolt (1/2″-13 x 3″) – Zinc Plated

In the demanding environment of professional agriculture, the reliability of a machine is only as strong as the fasteners that hold it together. This SYZAGRI Heavy-Duty Hexagonal Threaded Bolt (1/2"-13 x 3") is engineered for critical structural and mechanical assemblies where high-tensile strength and environmental resistance are required. From tractor suspension components to implement frame bolting, this component provides the secure, vibration-resistant connection point your field operations demand.We know that agricultural hardware is subject to constant stress—heavy load cycling, high-vibration environments, and exposure to corrosive soil moisture. That’s why we manufacture our bolts from high-strength steel and finish them with a durable white zinc plating. This ensure maximum resistance to rust and environmental wear, keeping your equipment productive and out of the workshop. The precision-machined 1/2"-13 UNC (Unified National Coarse) threads ensure a reliable fit with standard lock nuts and tapped holes, eliminating the risks of stripping under heavy torque.As a field-hardened engineering partner, SYZAGRI focuses on providing components that match or exceed industrial equipment specifications. Whether you are performing field repairs during the peak harvest season or refreshing your machinery’s frame hardware, this threaded bolt provides the engineering integrity your fleet demands. At SYZAGRI, we don't just provide fasteners; we provide the reliable engineering that allows you to focus on the work ahead with confidence.
