HOLO-KROME紧固件的市场与螺纹紧固件的需求一样大，以将金属部件保持在一起或彼此调整。无论何处需要螺钉来执行其牢固固定金属部件的基本功能，同时允许在维修，更换或调整时准备好分离零件，HOLO-KROME内六角螺钉的类型和尺寸从长远来看，以更低的成本更轻松，更快速，更可靠地完成工作。

几乎没有一个行业可以命名为不需要HOLO-KROME产品。在制造和加工日常生活中使用的各种商品的工具和机器中;在通信，运输，农业，采矿和建筑等广泛领域。你会发现HOLO-KROME产品在工作中无数的地方，准备完成他们坚决抵抗每一个驱逐力量的重要任务。

自1929年成立以来，HOLO-KROME一直走在紧固件开发和创新的前沿。该公司围绕当时的革命性想法进行组织 - 通过金属成型或前进而非加工来制造插座螺钉。HOLO-KROME延伸其的创新传统，后来发明了“冷锻”工艺，其中金属经过预热处理，以提高其成型的可塑性。

HOLO-KROME的冷锻技术使套筒螺钉更精确，提供更大的强度并提供更高的抗疲劳性。HOLO-KROME的产品因其均匀性而受到认可，并且几乎没有其他劣质产品中的爆裂，微小裂缝，撕裂和破裂。

质量通常被定义为符合规范，并且在HOLO-KROME中花费了大量精力来确保所运输的产品确实满足所需的规格。从原材料订单的放置，到成品的运输和认证，HOLO-KROME程序和规范被应用以满足该目标。

所需规范的定义需要一些讨论。 HOLO-KROME的产品与任何制造商的产品一样，必须符合某些标准。这些标准的定义可以通过几种方式完成。当人们寻找一种简单的方法来定义产品时，人们常常会参考“行业标准”。实际上，任何制成品必须具有两组特征：尺寸，控制尺寸和形状，以及机械，控制基材和产品的性能。在紧固件行业中，有许多组织为该产品编写标准或规范。例如，在套筒头螺钉的情况下，一套适用的标准是ASME / ANSI B18.3，它定义了该产品的尺寸特征，ASTM A574定义了机械性能。这两者都非常详细，一方面提供了基本的尺寸定义，如直径，长度和螺纹尺寸，以及表面光洁度，同心度和制造方法，另一方面基本化学，热处理，硬度，拉伸强度和其他冶金特性，以及建立它们所需的测试已正确完成。

HOLO-KROME的原材料规格旨在提供能够正确制造所需产品的材料，而不会产生可能有害的固有缺陷。收到材料后，检查确认它是否符合这些规格，然后分配实验室编号，这将在整个制造，测试，存储和装运过程中提供全息代码可追溯性。

从第一台机器的第一台设备开始，校准的量具和控制图用于确保与已分配的印刷品的一致性，并且在热处理时，利用气氛控制的炉子，进行测试以进一步证实遵守规范。对于特殊产品，客户可以要求其他规格以满足其特定需求。对于我们正在讨论的产品类型，存在许多规范，并且这些规范的选择是买方和卖方之间的协议问题。在大多数情况下，使用“工业标准”，这是上面所示的组合，用于内六角螺钉。

提供所有这些保证所需的成分在于HOLO-KROME的人员，他们接受过执行所需检查和测试所需的各种艺术和技能的培训。除了这些人和他们的技能是他们使用的物理工厂和设备。从最新型螺纹规，激光测量设备到自动化设备，以及相应的测试设备，HOLO-KROME已经投入了足够的资金来保证满足规范要求。

HOLO-KROME这种对质量的投入是一种公司理念，从最高管理层到最后一台包装机。质量是每个人的工作，HOLO-KROME组织中的每个员工都意识到这一事实，而且非常重要。在工厂中使用相关参与组来帮助解决范围比单个机器更广泛的问题，并且已经证明这些问题在HOLO-KROME理念的持续改进方面是成功的。

The market for HOLO-KROME fasteners is as great as the need for threaded fastenings to hold metal parts together or adjust them to one another. Wherever screws are called for to perform their basic function of fastening metal parts securely, at the same time permitting ready separation of the parts in the event of repairs, replacements or adjustments, there is a style and size of HOLO-KROME hex-socket screw to do the job more easily, more quickly and more dependably -- at lower cost in the long run.

Hardly an industry can be named that doesn't need HOLO-KROME products. In the tools and machines that make and process the great variety of commodities used in everyday living; in the broad fields of communication, transportation, agriculture, mining and construction. You will find countless places where HOLO-KROME products are on the job, prepared to fulfill their important assignment of holding firmly against every dislodging force.

Since its formation in 1929, HOLO-KROME has been at the forefront of fastener development and innovation. The company was organized around what was a revolutionary idea at the time - the manufacture of socket screws by metal forming or heading rather than machining. Extending our heritage of innovation, we later invented the "Cold-Forged" process in which the metal is pre-warmed to improve its plasticity for forming.

HOLO-KROME's Cold-Forging techniques result in socket screws which are more precise, offer greater strength and afford higher fatigue resistance. Our products are recognized for their uniformity, and for being virtually free of the bursts, minute cracks, tears and fractures sometimes found in other, inferior products.

Quality is frequently defined as conformance to specification, and at HOLO-KROME a great deal of effort is expended in ensuring that the products shipped do, in fact, meet the required specification. From the placing of the raw material order, through the shipping and certification of the finished product, HOLO-KROME procedures and specifications are applied to meet that objective.

The definition of the required specification requires a little discussion. HOLO-KROME's products, like those of any manufacturer, must meet certain criteria. The definition of those criteria can be done several ways. It is common for people to refer to an "Industry Standard," when they are looking for an easy way to define a product. Actually, any manufactured article must, of necessity, have two sets of characteristics: the dimensional, controlling the size and shape, and the mechanical, controlling the base material and the performance of the product. In the fastener industry, there are many organizations which write standards or specifications for this product. In the case of socket head cap screws, for instance, one set of applicable standards would be the ASME/ANSI B18.3, which defines the dimensional characteristics of this product, and ASTM A574, which defines the mechanical properties. Both of these are quite detailed, providing on the one hand, basic size definitions such as diameter, length and thread size, as well as surface finish, concentricity and method of manufacture, and, on the other hand the basic chemistry, heat treatment, hardness, tensile strength and other metallurgical characteristics, as well as the tests necessary to establish they have been done correctly.

HOLO-KROME's specification for raw material has been designed to provide material which will properly make the desired product, without inherent flaws that might be harmful. When the material is received, it is inspected to be sure that it does meet those specifications, and then a Lab Number is assigned, which will provide Holo-code traceability throughout manufacturing, testing, storage and shipment.

From the first set-up on the first machine, calibrated gages and control charts are used to ensure conformance to the prints which have been assigned, and at heat treatment, utilizing atmosphere-controlled furnaces, testing is performed to the further corroborate adherence to specification. In the case of special products, the customer may request other specifications to meet his own particular needs. There are many specifications in existence for the type of product we are discussing, and the selection of these specifications is a matter of agreement between purchaser and seller. In most cases, the "Industry Standard" is used, which is the combination shown above, for socket head cap screws.

The ingredient necessary to provide all of these assurances lies in HOLO-KROME's people, who are trained in the various arts and skills needed to perform the checks and tests required. In addition to these people and their skills is the physical plant and equipment which they use. From indicating thread gages of the latest type, and laser measuring equipment, to automated devices to create metallographic specimens, as well as appropriate testing equipment, the investment has been made to have available whatever is required for assurance that the specifications are being met.

This devotion to quality is a company philosophy, from top management to the last packer on the line. Quality is everybody's job, and every associate in the HOLO-KROME organization is aware of that fact, and very much a part of it. Associate Involvement Groups are used in the plant to help solve problems which are broader in scope than a single machine, and these have proven to be successful in the drive for continuous improvement which is the HOLO-KROME philosophy.
