The 4.8-grade Hex Head Bolts are a category of fasteners made from medium-strength carbon steel, suitable for general-purpose applications. These bolts feature a hexagonal head, allowing for easy installation and removal using a standard wrench or socket. The "4.8" designation refers to the bolt's mechanical properties: a tensile strength of 400 MPa and a yield strength of 320 MPa, making them appropriate for non-critical connections where high strength is not essential.

Ideal for light to medium-duty construction, machinery, and automotive applications, 4.8-level Hex Head Bolts are cost-effective and widely available. They come in various lengths and diameters, providing versatility for different project requirements. These bolts typically have a zinc or plain finish to resist corrosion under normal conditions. Their ease of use, reliability, and affordability make them a popular choice for both professional and DIY projects.
