Specification

SEODescription

The Big Head Carriage Bolt M10x130, also known as a Heavy Duty Carriage Bolt M10 or Coach Bolt with Square Neck, features a robust design with a domed head and integrated square neck to prevent rotation during installation. With a 10mm diameter and 130mm length, it provides high tensile strength (typically Grade 8.8) for structural stability. Designed for direct integration into heavy machinery, construction frameworks, and agricultural equipment, this bolt operates effectively across wide temperature ranges (-40°C to +120°C) and withstands industrial-grade vibration. Its square neck ensures secure embedding in wood or metal substrates without separate fastening components. Key advantages include corrosion-resistant zinc plating, anti-loosening properties, and compatibility with standard M10 nuts. Limitations include mandatory pre-drilled square holes for installation and reduced flexibility in dynamic load applications. Primarily used in bridge construction, rail systems, and heavy equipment assembly industries.
