This hex cap screw is a Grade 8 fastener, manufactured from heat-treated alloy steel. Its yellow zinc plating provides enhanced corrosion resistance over plain or black oxide finishes. Grade 8 bolts offer a higher tensile strength and proof load compared to common Grade 5 or unrated fasteners, making them suitable for applications requiring superior clamping force and resistance to shear stress.
Used in heavy machinery, automotive suspension components, and structural steel connections, this bolt resists stretching and breaking under high stress. The yellow zinc finish offers moderate protection against rust and white corrosion in outdoor or damp environments, maintaining its integrity over extended service periods.
