Socket countersunk flange bolts are fasteners with a cylindrical head designed to sit flush with the surface of the material they’re fastened to. They feature a hexagonal socket drive for easy installation using an Allen wrench. The flange provides additional surface area, distributing the load and enhancing stability. These bolts are commonly used in applications where a clean, flat finish is required, making them ideal for machinery, automotive parts, and furniture assembly.For quotes,inquiries,or custom bolts request, please feel free to click the button”get a free quote”.

Flange bolt is a type of bolt used for connecting flanges. It is typically composed of three parts: a hexagonal head, a flange, and a threaded rod. Like flange nuts, it also have a flange plate.The hexagonal head and the flange are fixed together, while the rod is a cylindrical part with external threads. Flange bolts are generally used together with nuts.
1.Before installing the flange, the flange bolts must be placed in the flange holes to ensure that each hole has a bolt installed.
2.The flange bolts must be rotated backward under the flange, and then the flange should be placed on the flange bolts.
3.Before installing the flange nuts, the flange must be rotated 90 degrees to ensure all the flange holes are aligned in a straight line.
4.Before tightening the flange nuts, they must be tightened in a crisscross pattern, starting by tightening the bolt in hole 1, then tightening the corresponding bolt in hole 4, followed by tightening the bolts in holes 2 and 3.
5.Repeat the above steps until all the flange nuts are tightened to the standard torque.
1.Bolts and nuts of the same material and strength grade as the flange should be used.
2.The bolt length should be slightly longer than the combined thickness of the flange and gasket to ensure proper fastening and sealing.
3.The nuts should only be tightened after the flange bolts are correctly installed to ensure the flange is accurately positioned.
4.A torque wrench should be used to tighten the flange nuts, following the specified torque values and tightening them one by one.
5.Before tightening the flange nuts, the surface of the flange and the coating (black or blue) on the bolts and nuts should be cleaned to avoid misjudging the tightness.
