Thread: Coarse Thread length: Partial Thread standard: Metric Strength class: 12.9 Finish: Zinc plating Key benefits - High strength performance The metric class 12.9 rating indicates high tensile strength for demanding fastening applications. - Efficient installation Coarse threads enable quicker driving and more forgiving alignment in rough or soft materials. - Targeted clamping and fit Partial thread provides a defined unthreaded portion for controlled engagement and load transfer where full-threaded fasteners are not required. - Corrosion resistance Zinc plating adds a protective layer to improve durability in typical indoor or exterior environments. Why you need this fastener - When a strong, reliable connection is required in metric threaded assemblies. - When you need a fastener that installs quickly without compromising strength. - When corrosion resistance is beneficial to extend service life. Specifications at a glance - Thread: Coarse - Length: Partial Thread - Thread type: Metric - Strength class: 12.9 - Finish: Zinc plating Compatibility and usage guidance - Designed for use with corresponding metric nuts and components that accept coarse metric threads. - Suitable for applications where a partially threaded fastener provides the correct grip length and load distribution. - Best used in assemblies requiring high strength and resistance to corrosion relative to plain coatings. Practical use scenarios - Machinery mounting and bracket assemblies that require a strong fastener with a defined unthreaded portion for precise alignment. - Automotive components where high torque capacity and corrosion resistance are important for long-term reliability. - Outdoor equipment installation or damp-environment hardware where zinc plating helps protect against rust.
