Product Details

This product is a 10.9 grade fully threaded hex bolt, manufactured strictly according to DIN933. It is a high-strength, general-purpose bolt, distinct from the 10.9S bolts specifically designed for main frames. This product is suitable for non-core but heavy-duty connection scenarios such as secondary main frames of steel structures, heavy equipment bases, and steel structure supports. The product features a fully threaded design, with the thread covering the entire bolt, allowing for flexible adjustment of the installation depth and adaptability to connections of components of varying thicknesses. Made of high-quality alloy steel, it undergoes professional heat treatment to meet strength standards. Each batch undergoes hardness and tensile strength testing, ensuring stable quality. German standard specifications are suitable for overseas engineering projects and replenishment needs of traders, and are commonly used fasteners in steel structure engineering and industrial equipment installation.
