Rough Large Square Head Bolt

The volume of the rough large square head bolt is one circle larger than that of an ordinary bolt. Also known as thick square head bolt or heavy square head bolt.The square head part is particularly wide and feels heavy when held in hand. Its surface has not undergone fine grinding, retaining obvious processing marks, and the threads are also rather rough.

Parameters

Product feature

The Square Head width and screw diameter of the rough large square head bolt are both larger than those of ordinary bolts, and the materials used in production are very thick. They are generally made of high-strength steel and can withstand tensile forces of several tons or even dozens of tons. Even if they are subjected to force for a long time, they are not prone to deformation or breakage.

Applications

The rough large square head bolt will be used in the construction of offshore oil platforms. Offshore oil platforms are subject to the impact of wind and waves all year round and have extremely high requirements for connecting components. The thick square head bolt can be used for the connection of the platform steel frame. It can not only bear the weight of the platform itself, but also resist the force of sea breeze and waves, ensuring the stable operation of the platform in harsh environments.

Heavy square head bolts will be used when building Bridges. The connection between steel beams and steel columns requires bolts that can withstand the heavy pressure of vehicles and wind force to ensure the safety of vehicle operation. The rough surface can prevent loosening caused by long-term vibration and ensure the safety of the bridge.
