An Ortman key is made of elongated rectangular metal bar stock, such as steel, and is inserted into juxtaposed annular grooves around the circumference of the mating parts. The Ortman key assembly is used in high-pressure applications where packaging, strength and mass are important. The Edmund key is a common variant of the Ortman key which is similar except has a feature added to the end of the key to aid in extraction of the key from the assembly. == References == - [[Building Construction/Construction & Materials/Building Material/Polymers and Composites]] - [[Design/Building Typologies/Healthcare Architecture]] - [[Structures/Structure Systems & Design]] - [[Professional Practice/Legal and Liability]] - [[Building Services/Building Performance/Indoor Air Quality]] - [[Design/Architectural Design/Design Process]] - [[Professional Practice/Construction Management/Quality Control]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 2 - Soils and Foundations]] - [[Urban and Planning/Transportation Planning]] - [[History and Theory/Temple Architecture/Stone Temples of India/pillars]] Google Patent Search Ortman Key G.
