Black DIN933 DIN931 ASTM A325 A490 ISO4041 Structural Bolt Heavy Hex Head Bolts
DIN933 DIN931 ASTM A325 A490 ISO4041 Structural Bolt Heavy Hex Head Bolts, it has different sizes and stabdards.
ASTM A325 is an ASTMstandard 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 12 to 1-12 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 M1236.There is also a T version, which is used to refer to fully threaded bolts.
This is a standard set by the standards organization ASTM, a voluntary standards development organizations that sets technical standards for materials, products, systems, and services.
Hex screws, standard parts, fasteners widely used in various mechanical equipment, electronic products, communications equipment, furniture and equipment, construction and other sectors of production, installation and maintenance.About installation,to achieve the best installation result, it is important to use a properly manufactured riveting tool (see page 84). It is recommended to use a clamp to achieve a constant result. Small amounts can also beinstalled by hand tools.
