Specifications of chemical anchors

‌The specifications of chemical anchor bolts mainly include two parameters: diameter and length. These specifications directly affect their load-bearing capacity and scope of application. ‌Common chemical anchor bolt diameter specifications include M8, M10, M12, M16, M20, M24 and M30. The larger the diameter, the stronger the load-bearing capacity. For example, M8 chemical anchor bolts are suitable for fixing small loads, while M30 is suitable for fixing extremely heavy loads. ‌ The length specification of chemical anchor bolts is also very important. Common lengths include 70mm, 90mm, 100mm, 120mm, 140mm, 160mm, 180mm and 200mm. The length selection depends on the thickness of the object being connected and the depth of the bolt penetration. For example, the length of M8 chemical anchor bolts is generally 70mm or 90mm, while the length of M24 chemical anchor bolts may reach 220mm or 250mm. In addition, the specifications of chemical anchor bolts also include national standard models and non-standard models. National standard models are produced according to national unified standards and have wide applicability and interchangeability; non-standard models are customized according to specific engineering needs and have higher flexibility and pertinence. Strength grade and material type are also important specification parameters. Common strength grades include 4.8, 5.8, 8.8, etc. Material types include carbon steel chemical anchor bolt and stainless steel chemical anchor bolt, etc. Different materials have different strength and corrosion resistance.
