DIN933 DIN931 ASTM A325 A490 ISO4041Black Structural 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 ASTM 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 1⁄2 to 1-1⁄2 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. 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.

In order to achieve the best possible joint, it is recommended to install the screw through the opposite side of the head, although it is possible to install the screw from the top face side. Production process: wire rod, wire drawing, drawing, cold forging, threading, dipping, inspection, packing, shipment.
The hex head bolts are be used in connecting.
