Product Description

The Big head carriage bolt M8x60, also known as Large head M8*60 bolt or M8-60 heavy duty carriage bolt, is a specialized fastening component designed for structural applications requiring enhanced load distribution. Featuring an M8 thread diameter and 60mm shank length, its oversized dome head integrates a square neck to prevent rotation during installation. This bolt typically supports direct mechanical connections in steel frameworks, wooden assemblies, or heavy machinery, operating across industrial temperature ranges (-20°C to +150°C) without performance degradation. Preferred in construction, automotive, and agricultural equipment sectors, its advantages include superior shear resistance and vibration-proof design, though the large head profile may limit use in confined spaces. The zinc-plated steel construction ensures corrosion resistance for outdoor applications.
