Grade 8.8 Short Neck Carriage Bolts conforming to DIN603 standards are high-strength fasteners designed for demanding applications. These bolts feature a mushroom-shaped head and a short square neck, which prevents rotation during installation. The Grade 8.8 classification indicates their high tensile strength, making them suitable for heavy-duty use in construction, machinery, and engineering projects. The bolts are often made from alloy steel and can be treated with various finishes, such as hot-dip galvanizing, to enhance corrosion resistance. They are typically used with nuts and washers to ensure secure and stable connections.
