Thanks to the electrolytic galvanization, the bolt is excellently protected against corrosion, significantly extending its lifespan. ### Technical specifications - **Diameter**: M12 - **Length**: 50 mm - **Thread length**: 30 mm - **Head height**: 6.9 mm - **Head diameter**: 30.6 mm - **Nut width across flats**: 19 mm - **Material**: Steel, strength class 4.6 - **Surface treatment**: Electrolytically galvanized - **Standard**: DIN 603/555 ### Benefits of electrolytic galvanization Electrolytic galvanization provides a thin, uniform zinc layer that effectively protects the steel against rust. This process ensures a smooth surface, making installation easier and improving the aesthetics of the fastening. ### Application possibilities This carriage bolt is ideal for: - **Wood constructions**: The domed head and square neck ensure a firm anchoring in wood, preventing rotation. - **Metal connections**: Suitable for connecting metal parts where a flush finish is desired. - **Automotive applications**: Widely used in the automotive industry for fastening parts where a smooth head is necessary. ### Installation instructions 1. **Pre-drilling**: Drill a hole with a diameter of 12 mm at the desired location. 2. **Placement**: Insert the bolt through the material, ensuring the square neck is properly recessed to prevent rotation. 3. **Securing**: Tighten the supplied hex nut with a 19 mm wrench until the connection is secure. ### Maintenance and durability Although electrolytic galvanization offers excellent protection against corrosion, it is recommended to periodically inspect the bolts, especially in humid or aggressive environments. If the zinc layer is damaged, additional protection may be needed to ensure longevity. ## Breadcrumbs - [Fasteners](https://www.auto-service.be/en/fasteners) - [Bolts](https://www.auto-service.be/en/fasteners/bolts) -
