Non standard bolts are often used in daily life, ranging from watches and glasses to trains, ships, and space shuttles. Bolt is an invention in people’s production, and according to the application field, it is also the pride of mankind. What are the precautions for using bolts
Role of non-standard bolts:
The main function of non-standard bolts is to link and fasten machine parts, which can also be called special-shaped bolts. There are many bolts that can be connected without nuts. Of course, those that do not use nuts are basically non-standard screws, which play a key role in connecting parts.
Material of non-standard bolts:
Generally speaking, non-standard bolts are manufactured from materials such as high carbon steel, medium carbon steel, and low carbon steel. The carbon content in carbon steel materials can be divided into low carbon steel, medium carbon steel, high carbon steel, and alloy steel.
Countersunk and semi countersunk head bolts are widely used because they do not protrude from the surface of the product and affect its appearance after being screwed into the product. They are mostly used on the outside of the product.
Hexagon head is also a common head type in bolt fasteners. Some hexagon head fasteners also have a table, a hole, a boss, and a flange surface. Hexagon head bolts have high mechanical properties and are easy to tighten with a wrench. It can also apply a large tightening torque and is widely used. The bearing surface is provided with a boss or a hexagon head bolt with a flange surface, and it also serves as a gasket. Increasing the pressure bearing surface has a good anti loosening effect. It can also be used for connecting steel structures and important host structures.
Pan head bolts can have slotted, cross recessed, and plum blossom grooves on their heads, mainly for the convenience of using tools for screwing. They are mostly used in products with low strength and low torque, and are generally used in small size host products such as household appliances.
The function of the large flat head, semicircular head, square neck, and tenon is to fix the screw, while the screwing device is to fasten the connection of metal parts. Generally, slotted half round head screws are mostly used in situations where the space is small and the force is not large, while flat round heads are mostly used for the connection and fixation of thin-walled component plate structures.
The company mainly produces long bolts, non-standard bolts, titanium bolts, small bolts, stainless steel bolts, etc
