ASTM A307b GRB Heavy Hex Bolts is a ASTM A307 models.The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application. Refer to the Mechanical Properties Chart for the subtle strength differences within each grade.

ASME Black Half Thread Hex Bolt Class 8.8 steel screws are suitable for fastening most machinery and equipment. To maintain corrosion resistance, use ASME Black Half Thread Hex Bolt with black ultra-corrosion-resistant-coated nuts and washers.

JIS1190 Bhex Nut with Flange provide a secure and tight fit, while also preventing the nut from loosening due to vibration. This is especially important in industries where machinery and other heavy equipment are used, as any loosening of fittings can cause dangerous and costly consequences. The flange of JIS1190 Bhex Nut with Flange acts as a washer, providing additional support while preventing the nut from embedding itself into the surface of the material being fastened. This greatly reduces the risk of damage to the structure, as well as providing a more aesthetically pleasing finish.

14399 Black HDG Heavy Hex Bolts is usually used with a nut and a washer, 14399 Black HDG Heavy Hex Bolts has several types such as: En14399-3 En14399-4 En14399-5 En14399-6. En14399 is also DIN6914, Bolt and nut gaskets are used in combination. 14399 Black HDG Heavy Hex Bolts is usually black. Bolts, nuts and gaskets have hr or hv.

As1252 Heavy hexgonal Bolt are commonly used in critical structural applications such as Bridges, buildings and other infrastructure. Ensuring their quality is critical to the safety and structural integrity of these works. The control and traceability of the A325M heavy duty hex bolt or any fastener is a key aspect of the construction and engineering industry. Safety and structural integrity are the correct applications that distinguish As1252 Heavy hexgonal Bolt. Batch control and traceability help maintain the highest safety standards. Batch control ensures that the bolts used in the project come from the same production batch. This helps maintain consistent quality and ensures that all bolts from a particular batch meet the same specifications and standards. In the rare cases where defects or problems are found in a particular batch of bolts, being able to trace back to the source of those bolts can facilitate an effective recall and replacement. This minimizes downtime and project delays.

DIN933 Hex Bolt is the most commonly used hex bolt in the metric bolt, DIN933 Hex Bolt common grades are 4.8, 6.8, 8.8, 10.9, 12.9. DIN931 Hex Bolt surface is coated with different coatings for different environments.
