Get Iso898 1

ISO 898-1 Class 12.9 material is known for its exceptional strength, featuring a tensile strength of at least 1220 MPa. This class of fasteners is ideal for high-performance applications, such as in heavy machinery and load-bearing structures. Opting for Class 12.9 materials can significantly improve the reliability and safety of your assemblies. Always consider this class if you require robust, high-strength solutions.

ISO 898-1 Class 10.9 material refers to a specific grade of high-strength bolts designed for demanding applications. This class demonstrates a tensile strength of 1040 MPa, making it suitable for various construction and engineering contexts. Using Class 10.9 components ensures that your assemblies can withstand considerable loads and stresses. It's essential to choose the right material to enhance your project's durability.

ISO 898-1 is often compared to ASTM standards, specifically ASTM A325 and A490. These standards guide the mechanical properties of bolts, nuts, and fasteners. Understanding these equivalents helps manufacturers and users ensure they meet international quality and safety requirements. By familiarizing yourself with these standards, you can make informed choices for your projects.

ISO 898 outlines the specifications for different grades of fasteners and their corresponding performance criteria. It provides detailed guidance on the tensile strength, yield strength, and hardness of various fasteners, which are critical for ensuring safety and efficacy in applications. For companies looking to comply with international standards, this norm serves as a foundational guideline. By integrating ISO 898 into your processes, you can improve product safety and customer satisfaction.

ISO 898-1 is an international standard that specifies the mechanical properties of fasteners made of carbon steel and alloy steel. It primarily covers bolts, screws, and nuts. Understanding this standard can help manufacturers ensure that their products meet global quality benchmarks. By adhering to ISO 898-1, businesses can enhance their reputation and reliability in the marketplace.

The ISO 898-1, ISO 3506-1 and ASTM F606 standards describe tests on threaded fasteners (bolts, screws and studs) including steel screws and their mechanical and physical properties such as tensile strength, offset yield (minimum stress), elongation after fracture and hardness.

ISO 898 is an international standard that defines mechanical and physical properties for metric fasteners. This standard is the origin for other standards that define properties for similar metric fasteners, such as SAE J1199 and ASTM F568M.

ISO 898-1:2013 specifies mechanical and physical properties of bolts, screws and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10 °C to 35 °C.
