Product Description

The M6 carriage bolt 140mm features a large head design (specified as M6x140mm big head bolt) for enhanced load distribution and secure fastening. Constructed with a threaded shaft (M6 diameter, 140mm length) and a smooth, domed head, it eliminates rotation during installation, ideal for wood or metal assemblies. Typically made from carbon steel or stainless steel, it operates under a broad temperature range (-20°C to 120°C) and suits automotive, construction, and industrial machinery applications. The large head carriage bolt provides high shear strength, corrosion resistance (varies by material), and simplified alignment due to its non-threaded neck. Drawbacks include limited suitability for dynamic loads and potential head protrusion in space-constrained setups. No integrated electronics, power sources, or communication interfaces are present, as this is a purely mechanical fastener.
