Carriage bolts, characterized by their rounded heads and square necks, are designed to be inserted into a pre-drilled hole. The unique shape of the head provides a clean and finished look, while the square neck prevents the bolt from turning when a nut is tightened. This makes carriage bolts exceptionally useful in situations where aesthetics are important, such as in furniture or architectural structures.

Another important characteristic is compatibility with various bolt sizes. Zinc hex nuts come in a range of sizes, allowing them to be paired with different bolt diameters and thread pitches. This versatility makes them suitable for a wide array of applications, from household projects to heavy machinery and industrial structures.

DIN 975 threaded rods are utilized in a wide range of construction and engineering applications, including structural support, bracing, anchoring, and fastening. The 10.9 grade designation ensures that the threaded rods offer high tensile and yield strength, making them suitable for heavy-duty applications where a strong and reliable attachment is essential. When selecting DIN 975 threaded rods, factors such as material composition, diameter, length, and grade should be considered to ensure compatibility with the specific project requirements and load capacities.

3. Width Across Corners The width across corners of an M8 nut is approximately 13 mm. This size is crucial for socket or wrench fitting, facilitating easy tightening and loosening.
