Title:Screw Threads, Metric Buttress - Mjb Profile
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This standard specifies the characteristic of the MJB metric series of buttress screw threads based on 7掳/45掳 form, with width of truncation same as MJ screw thread profile, and with a controlled radiused root in the external thread. This standard establishes the basic triangular profile for the MJB thread form, the design profiles, standard pitches, tolerance classes, formulae for tolerances and dimensions, tolerance tables, and a system of designations. Because of the specialized application for buttress threads, no preferred diameter-pitch series have been established for this standard and each application will require use of the thread formulae for dimensions and related tolerances given herein for deriving the thread dimensional requirements.【英文标准名称】:Gascylinders-Cylinderbundles-Design,manufacture,testingandinspection.
