Heavy hex bolt manufacturing and removal method
What is the manufacturing process of heavy hex bolts? How to remove heavy hexagon bolts? Let's take a look at the manufacturing and dismantling methods of heavy hexagon bolts. I hope to help everyone.
Method for manufacturing heavy hexagon bolt
The production of heavy hexagon bolts is generally started from the purchase of screw wire. What kind of heavy hexagon bolts are required to purchase the same type of screw wire. Also determine the weight of the hexagonal bolts, for example, some are stainless steel bolts, some are 4.8-level hexagonal head screws, some are 8.8 heavy hex bolts, and some are 12.9 heavy hex bolts. These determine the material of the screw wire material, whether it is iron or stainless steel, and what grade of carbon steel is used.
Then, the mold is ordered according to the heavy hex bolts. After that, the head is turned, and then the fangs are smashed, and the hex bolts are threaded to make them pass the stop gauge. If it is a stainless steel heavy hex bolt, it needs to be cleaned and dried. Some require high levels of passivation to make the salt spray longer. Some iron heavy hex bolts need to be electroplated and then electroplated, summarizing the customer's requirements and plating different colors.
Heavy hex bolt removal method
Heavy hex bolt refers to the fastener composed of the head and the screw. The bolt is divided into iron bolt and stainless steel bolt according to the material, that is, hex head bolt (partial thread)-C-class and hex head bolt (full thread)-C grade, and Hex head bolts (rough), hex head bolts, black iron screws.
Heavy hex bolts are often used on machinery. They are mainly for easy fastening, disassembly, and are not easy to slip. The hex wrench is usually a 90° turn. The bent end is long and short, and when the screw is short with one side, the hand Holding the long side can save a lot of force and can better tighten the screw. The long end has a round head (hexagonal cylinder like a sphere) and a flat head. The round head can be easily removed and removed, and some installations are inconvenient. The part of the wrench. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon. It also has a screw head (the position of the wrench) is thinner than the inner hexagon, and some places are not replaced by the inner hexagon. In addition, the cost is low and the power is small. For machines with low precision requirements, heavy hexagon bolts are much less than external hexagons.
The above is about the manufacturer and removal method of heavy hexagon bolts. I hope everyone can understand the manufacturing and removal methods of heavy hexagon bolts.
