ASTM A325
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled ''Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength''. It defines mechanical properties for bolts that range from in diameter. The equivalent metric standard is ASTM A325M, which is titled ''Standard Specification for Structural Bolts, Steel, Heat Treated 830 MPa Minimum Tensile Strength''. It defines mechanical properties for sizes M12–36.. This is a standard set by the standards organization ASTM International, a voluntary standards development organizations that sets technical standards for materials, products, systems, and services. In 2016, ASTM officially withdrew specification A325 and replaced it with ASTM F3125. To minimize confusion, bolt head markings are unchanged and the designation A325 is retained as a grade name within the new standard. In 1951, A325 bolts were recognized as equivalent to a hot driven ASTM A141 rivet. Types The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASTM International
ASTM International, formerly known as American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Some 12,575 ASTM voluntary consensus standards operate globally. The organization's headquarters is in West Conshohocken, Pennsylvania, about northwest of Philadelphia. It is founded in 1902 as the American Section of the International Association for Testing Materials (see also International Organization for Standardization). History A group of scientists and engineers, led by Charles Dudley, formed ASTM in 1898 to address the frequent rail breaks affecting the fast-growing railroad industry. The group developed a standard for the steel used to fabricate rails. Originally called the "American Society for Testing Materials" in 1902, it became the "American Society for Testing And Materials" in 1961. In 2001, ASTM official ...

Unified Thread Standard
The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. It has the same 60° profile as the ISO metric screw thread, but the characteristic dimensions of each UTS thread (outer diameter and pitch) were chosen as an inch fraction rather than a millimeter value. The UTS is currently controlled by ASME/ANSI in the United States. Origins : ''See the "History of standardization" section of the screw thread article.'' Basic profile Each thread in the series is characterized by its major diameter ''D''maj and its pitch, ''P''. UTS threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The outermost and the innermost of the height ''H'' of the V-sha ...

ASTM A490
ASTM A490 and ASTM A490M are ASTM International standards for heavy hex structural bolts made from alloy steel. The imperial standard is officially titled ''Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength'', while the metric standard (M) is titled ''Standard Specification for High-Strength Steel Bolts, Classes 10.9 and 10.9.3, for Structural Steel Joints''... In 2016, specifications A325 and A490 were officially withdrawn by ASTM and replaced by ASTM F3125. A325 and A490 heavy hex structural bolts are now grades under the new F3125 specification. Connection types There are also three connection types defined:. *SC: A slip critical connection. *N: A bearing type connection where the threads are on the shear plane. *X: A bearing type connection where the threads are not on the shear plane. Mechanical properties These bolts are equivalent to ASTM A325 bolts in application and geometry, but are made to a higher strength. The im ...

ASTM F568M
ASTM F568M is an ASTM International standard for metric bolts, screws and studs that are used in general engineering applications. It is titled: ''Standard Specification for Carbon and Alloy Steel Externally Threaded Metric Fasteners''. It defines mechanical properties for fasteners that range from M1.6 to 100 in diameter. The standard was withdrawn in 2012.. and has been replaced by ISO 898-1. This standard defines ''property classes'', the metric equivalent of a screw ''grade'', that are almost identical to those defined by ISO 898-1, except for the addition of the 8.8.3 and 10.9.3 classes. These two additional standards are fasteners that have the same mechanical properties as their base property class (i.e. 8.8 and 10.9), but are made from weathering steel. The standard is referenced by ASME B18.29.2M, which defines insert length selection for helical coil screw thread inserts. This is a standard set by the standards organization ASTM International, a voluntary standards develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt (fastener)
A bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. Bolts are very closely related to screws. Bolts vs. screws The distinction between a bolt and a screw is poorly-defined. The academic distinction, per ''Machinery's Handbook'', is in their intended design: bolts are designed to pass through an unthreaded hole in a component and be fastened with the aid of a nut, although such a fastener can be used without a nut to tighten into a threaded component such as a nut-plate or tapped housing. Screws in contrast are used in components which contain their own thread, or to cut its own internal thread into them. This definition allows ambiguity in the description of a fastener depending on the application it is actually used for, and the terms screw and bolt are widely used by different people or in different countries to apply to the same or varying fastener. Bolts are often used to make a bolted joint. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
