ASTM A193 ASTM A194 2H heavy hex metal bolt with heavy nut SUS304 Plain surface
1,Description:
Heavy-duty hexagon socket bolts are used for mechanical connections that bear relatively large loads.
Its specifications and models are diverse to meet the needs of different projects. Common diameters of heavy-duty hexagon socket bolts include M8, M10, etc. The pitch of M8 heavy-duty hexagon socket bolts is generally 1.25mm. The pitch of M10 heavy-duty hexagon socket bolts is usually 1.5mm. The length specifications of bolts range from tens of millimeters to hundreds of millimeters. Heavy-duty hexagon socket bolts with a length of 20mm are suitable for connecting thinner components. 50mm long heavy-duty Allen bolts can be used for fixing slightly thicker materials. There are specific standards for the head dimensions of heavy-duty Allen bolts.
The dimensions of the opposite sides of the head vary according to the specifications of the bolts. The thickness of the head is also designed in accordance with the corresponding specifications. In terms of materials, there are types such as carbon steel and alloy steel. The cost of carbon steel heavy-duty hexagon socket bolts is relatively low. Alloy steel heavy-duty hexagon socket bolts have higher strength. Surface treatment affects the anti-corrosion performance of bolts. Galvanizing treatment can enhance the rust resistance of bolts. The blackening treatment makes the appearance of the bolts more textured. The grades of heavy-duty hexagon socket bolts include 8.8 grade, 10.9 grade, etc. The tensile strength of grade 8.8 bolts is approximately 800MPa.
The standard for heavy-duty hexagonal bolts recommends the use of high-quality carbon cable structural steel and alloy structural steel, such as 45 steel, 35CrMo, etc. These materials can meet the performance requirements of bolts of different strength grades. The standard for heavy-duty hexagonal bolts also stipulates the length tolerance of the bolts. Generally, the length tolerance ranges from ± 1.5mm to ± 2mm, and the specific value is determined according to the length specification of the bolt. The standard also sets requirements for the shape and position tolerances of heavy-duty hexagonal bolts, such as the straightness tolerance of the bolt shank, which generally does not exceed 0.2mm/m, to ensure the installation accuracy of the bolts.
