Common specifications for Hex Bolt

The bolt is covered with a ring, which has a gap on it, and a hole is made in the wall when used. Place the anchor bolt into the hole and squeeze the ring when the bolt is tightened. This causes the bolt to get stuck in the hole and play a fixed role. A secondary casting method can be used, that is, a bolt hole of an appropriate size is reserved when the foundation is poured.
The thread is a shape having a uniform helix projection on the cross section of the outer or inner surface of the Anchor Bolt. According to its structural characteristics and uses, it can be divided into three categories: ordinary thread: the tooth shape is triangular, used to connect or fasten parts. Ordinary threads are divided into coarse teeth and fine thread according to the pitch, and the connection strength of the fine thread is high. Drive thread: The shape of the tooth is trapezoidal, rectangular, saw-shaped and triangular. Sealing thread: used for sealing connection, mainly for pipe thread, taper thread and taper pipe thread.
What materials does Hex bolt have? Hex bolt is divided into iron bolts and stainless steel bolts according to the material. Hex bolt is divided into stainless steel SUS202 hexagon socket bolts, stainless steel SUS304 cylinder head hexagon socket bolts and SUS316 stainless steel hexagon socket bolts.
Hex Bolt
There are several common specifications for Hex Bolt:
1. The hexagonal mouth is allowed to be slightly rounded or countersunk;
2. The end chamfer d<=M4 is the end of the tanning;
3, the length of the incomplete thread U <= 2P;
4, the top edge of the head may be round or chamfered, optional by the manufacturer;
5, the bottom edge can be round or chamfered to Dw, but no burrs;
6, Hex bolt standards: GB / T2672, GB / T2673, GB / T2674, GB / T6190 and GB / T6191.
As a China Bolt Spike Supplier, how much do you know about high-strength bolts? High-strength bolts are used for high-strength bolts on ultra-high-pressure equipment. In order to ensure the sealing of the container, a large pre-stress is required. Generally used for the connection of bridges, rails, high pressure and ultra high pressure equipment.
There are six characteristics of high-strength bolts, which are as follows:
1. the reliability is good. The high-strength bolt galvanized layer and the steel are metallurgically combined to become a part of the steel surface, so the durability of the coating is relatively reliable.
2. comprehensive protection, each part of the plated parts can be plated with zinc, even in the depressions, sharp corners and hidden places can be fully protected.
3. the processing cost is low, the cost of hot dip galvanizing rust is lower than the cost of other paint coatings.
4. save time and effort, the galvanizing process is faster than other coating construction methods, and can avoid the time required to paint on the construction site after installation.
5. Durable, in the suburban environment, the standard hot-dip galvanizing rust thickness can be maintained for more than 50 years without having to repair. In urban or offshore areas, the standard hot-dip galvanized rust layer can be maintained for 20 years without having to be repaired.
6. The toughness of the coating is strong, and the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.

Tension Clamp Is Important

图片
With the increase of the axle load of the railway locomotive and the improvement of the running speed of the train, as well as the development of the urban rail transit and the subway, the Tension Clamp  is also becoming a key link in the continuous development of the track structure, which is concerned by all the countries. In the general line, the need is about buckle pressure, good elastic spring, to meet the needs of heavy-duty, high-speed lines, while in the viaduct track seamless circuit, in order to reduce the interaction between the rail and the bridge, we have to ensure the elasticity that is enough, if the train goes through, the loss of undercover cushion due to compression caused by the buckle pressure is small, and fasteners of  Railway Fastening System  do not loose. Although it is a small public work device, but it is an important part of the track, because of its large demand, about 7000 per kilometer, its reliability is directly related to the safety...

Pay Attention to Rail Plate Base Pad

图片
As an indispensable part of the railway, the  Rail Plate Base Pad  plays an important role on the railway. If it falls off, which will influence the whole  Railway Fastening System  deeply. In the high-speed railway subgrade, the separation of the slab Rail Plate Base Pad will reduce the track strength. This situation means the stiffness and service life of the track will be reduced directly. It causes the rail plate base pad to crack and disconnects from the lug time. The pressure of the top surface of subgrade increases with the length of abscission. Meanwhile, the trend of increasing is becoming more and more obvious.

Do You Know Heavy Haul Rail?

图片
The first International Heavy Haul Congress in 1978 was held in Perth, Australia. Since the establishment of the International Association of Heavy Haul Transport in 1985, the definition of heavy railroads has evolved with heavy loads and advancing with the time. In 2005, the International Association of Heavy Load Associations proposed a new heavy haul railway standard that required to meet at least two of the following three conditions: 1.train traction quality is not less than 8000t 2.vehicle axle in the vehicle reach or exceed 27t 3.The length of the line is not less than 150 km, the annual freight volume is not less than 40 million tons. We support several types of  Rail Fastening System  to meet the different rail's requirements.
