Overview
ASME B18.2.2 is a dimensional standard used for threaded fastening components including standoffs and related hardware used in industrial and mechanical assemblies. It defines dimensional characteristics, thread compatibility, and fastening requirements to support reliable assembly performance. The standard is commonly referenced together with material, coating, and thread standards depending on the application requirements. ASME B18.2.2 components are commonly available in carbon steel, stainless steel, alloy steel, and corrosion-resistant finishes. When sourcing products to ASME B18.2.2, additional specifications may include thread size, material requirements, finish or coating, and certification requirements.
