ISO紧固件标准:“三巨头”刺激采用米制紧固件系统ISO标准
ISO fasteners standard: " the big three " stimulation using Metric Fasteners standard system ISO
通过供应商和终端用户采用ISO紧固件标准，结束40多年紧固件行业混乱。采用ISO标准是良好的工程实践，能简化库存，提高装配标准化程度，并使出口产品更具吸引力对美国以外的客户。
The supplier and user terminal using ISO Fastener standard fastener industry, ending 40 years of chaos. Using the ISO standard is good engineering practice, can simplify inventory, improve the assembly standardization degree, and export products more attractive to customers outside the USA.
    “三巨头”在美国刺激采用米制系统
The "big three " in the United States of America stimulation using the metric system
    美国开始使用米制紧固件，早在20世纪70年代，“三巨头”（福特、通用和克莱斯勒）就用显著的方式承诺对所有新车型设计，使用米制系统。因为汽车行业起头，至今使用米制螺纹紧固件比其他行业多，在美国的紧固件供应商开始参与米制紧固件的生产。采纳米制设计的汽车行业承诺，是在全世界将一个汽车设计付之生产，而不是有个北美的设计和北美以外所有市场的另一个设计。庞大的国际设备制造商如卡特彼勒Caterpillar和约翰迪尔JohnDeere马上效仿。
The United States began to use Metric Fasteners, early in the nineteen seventies, the "big three " ( Ford, GM and Chrysler ) with significant promise for all new vehicle design, using the metric system. As the industry started to use metric threaded fasteners, far more than other industry, in the United States of America fastener suppliers began to participate in Metric Fasteners production. Adoption of metric design in automobile industry is committed, all over the world will be a car design for the production, rather than a North American design and market outside North America all the other design. Large international manufacturers such as Caterpillar Caterpillar and John Deal JohnDeere immediately follow suit.
    直到那个时候，美国使用米制紧固件数量相对低。它们多数使用，对进口的欧洲产的维护保养上，大多对来自德国的设备维护。DIN（德国标准化研究所）系统作为德国标准系统被引用，及大部分进口紧固件使用在支持进口设备上，因为其产自欧洲用DIN紧固件标准。
Until that time, the United States of America using relatively low metric fasteners. Most of them use, the imported European maintenance, mostly from German equipment maintenance. DIN ( German Institute for Standardization ) system as German standard system is cited, and most of the imported fasteners used in support of imported equipment, because it produced in Europe with DIN fasteners standard.
    三巨头决定采用米制计量系统，影响了世界所有工业化国家的设计。汽车制造商希望其能源产品在世界各地和其零部件具有兼容性，无论在哪制造、采购或装配都行。这样决定驱使准则和共同使用的所有零部件，包括紧固件的世界标准需求。
Three giants decided to adopt the metric measurement system, which influences the world all industrialized countries design. Car manufacturers hope its energy products in the world and its parts and components with compatibility, no matter in which manufacturing, purchasing or assembly. Decision driven standards and common use of all parts, including fasteners world standard.
    ISO紧固件委员会已建立通用米制紧固件系统
ISO fastener Committee has established a general metric fastener system
    当时，几个欧洲和亚州国家已经有对自己设计的米制紧固件通过他们的国家标准定义。为使这些设计普及，ISOTC2紧固件委员会成立。由于当时最主要的米制紧固件标准是DIN标准，所以DIN标准成为米制紧固件标准体系的基础，而最终向ISO紧固件标准演变。
At that time, several European and Asian countries have to design their own metric fasteners through their definition of national standards. In order to make the design of universal, ISOTC2 fastener Committee was established. Because at that time the main Metric Fasteners standard is the DIN standard, so DIN becoming standard metric fasteners standard system based, and eventually to ISO fasteners standard evolution.
    虽然美国努力加入在ISO，但同时试图塑造一个独特的米制标准，称为最佳米制紧固件体系(OMFS)。这项工作一开始在工业紧固件技术委员会(IFI)进行，而后转移到美国机械工程师协会(ASME)B18委员会和美国试验和材料协会ASTMF16委员会的紧固件委员会及SAE紧固件委员会进行。
Although the United States to join in ISO, but at the same time, trying to create a unique metric standard, known as the best metric fastener system ( OMFS ). This work began in the industrial fastener Technical Committee ( IFI ), then transferred to the American Society of Mechanical Engineers ( ASME ) B18 Committee and the American Society for testing and materials ASTMF16 Committee fastener Committee and the SAE fastener committee.
    OMFS的概念背后是，在其他现有的米制紧固件系统中，用诸如限定螺纹系列只为粗牙螺纹来缩小选择范围。OMFS包括引入外键头设计来取代六角头，及对螺纹用新的量规系统努力提高螺纹的质量。
The concept of OMFS is behind, in other existing metric fastener system, such as defining thread series for coarse thread to narrow the range of options. The OMFS includes introducing foreign head designed to replace the six angle of the head, and the screw with a new system to improve the quality of thread gauge.
    在ASME、ASTM和SAE委员会中OMFS概念的影响，导致美国建立紧固件标准的整个系列。最终在OMFS中的独特想法计划消失，并由此演变成与ISO紧固件标准可互换，但不完全一样的标准。事后看来，美国的努力只是在米制紧固件技术上增加其他米制紧固件标准的选项，使实现的目标复杂化而不是简化。OMFS概念是高尚的，而目标却无法实现。
In ASME, ASTM and SAE Committee OMFS concept influence, led the United States to establish fasteners standard for the entire series. Finally in OMFS 's unique ideas disappeared, and thus evolved into a and ISO fasteners standard interchangeable, but not exactly the same as the standard. In hindsight, the efforts of the United States is in metric fastener technology by adding other Metric Fasteners standard options, so that achieve the goal of complex but not simple. The concept of OMFS is high, and the target can not achieve.
    在此期间，越来越多的国家加入ISO紧固件标准的努力，并因此建立了全球真正的紧固件标准系统。ISO紧固件标准的日益普及，使得许多国家撤消了自己国家规定的标准，与ISO标准接轨作为他们自己的米制紧固件体系。
During this period, more and more countries join the ISO fastener standards efforts, and thus established a global real fasteners standard system. ISO fastener standards have become increasingly popular, so many countries withdrew their own national standards, and ISO standards as their metric fastener system.
