ASME Fastener Standards

ASME, ASME Fasteners Standards, ASME Logo, The American Society of Mechanical Engineers

Founded in 1880 as The American Society of Mechanical Engineers, ASME is a nonprofit professional organization that enables collaboration, knowledge sharing and skill development across all engineering disciplines, while promoting the vital role of the engineer in society. ASME codes and standards, publications, conferences, continuing education, and professional development programs provide a foundation for advancing technical knowledge and a safer world.

ASME recently formed the International Society of Interdisciplinary Engineers (ISIE) LLC, a new for-profit subsidiary to house business ventures that will bring new and innovative products, services, and technologies to the engineering community.
