What Is The ASTM Standard Of Fastener?
The ASTM (American Society for Testing and Materials) develops and publishes standards for a wide range of materials, products, systems, and services. When it comes to fasteners, ASTM has several standards that cover various aspects, including dimensions, materials, testing, and performance requirements. Some commonly referenced ASTM standards for fasteners include:
ASTM F568/F568M – Standard Specification for Carbon and Alloy Steel Externally Threaded Metric Fasteners: This standard covers the chemical and mechanical requirements for carbon and alloy steel externally threaded metric fasteners.
ASTM F593 – Standard Specification for Stainless Steel Bolts, Hex Cap Screws, and Studs: This standard covers the requirements for stainless steel bolts, hex cap screws, and studs in diameters ranging from 1/4″ to 1-1/2″.
ASTM A193/A193M – Standard Specification for Alloy-Steel and Stainless Steel Bolting for High Temperature or High-Pressure Service and Other Special Purpose Applications: This standard covers alloy and stainless steel bolting materials for use in high-temperature or high-pressure service and other special applications.
ASTM A325 – Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength: This specification covers two types of quenched and tempered steel heavy hex structural bolts.
ASTM A490 – Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength: Similar to A325, this specification covers alloy steel bolts for use in structural steel connections.
It’s important to note that these are just a few examples, and there are many other ASTM standards that cover different types of fasteners and their specific requirements. Always check the specific ASTM standard that is relevant to the type of fastener you are dealing with for accurate information. Additionally, standards may be updated or revised over time, so it’s advisable to consult the latest version of the standards from the ASTM website or other reliable sources.
