Product Description

The M10 big head carriage bolt, also known as M10x25 carriage bolt or large head coach bolt M10, features a smooth domed head with a square neck measuring 15mm diameter and 5mm height. This DIN 603-compliant fastener uses M10x1.5 coarse threading over its 25mm shaft length (total length 40mm including head). Constructed from grade 8.8 carbon steel with zinc-plated finish, it operates in -30°C to 200°C environments and withstands 800MPa tensile strength. The integrated square neck prevents rotation during assembly, ideal for wood-to-metal joints in construction and railway infrastructure. Key advantages include vibration resistance and flush surface installation, though the permanent square neck integration limits retrofitting flexibility. Typical applications span structural frameworks, heavy machinery assembly, and transportation equipment requiring secure fastening under dynamic loads.
