What is the function of a stud stud Difference between a stud bolt and a stud stud

Answers for you. 1. Double-ended screws:

2. Function: generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, crane towers, long-span steel structures and large buildings.

This has two meanings, one is as upstairs said, the two ends are threads, the middle is a screw called a double-ended screw, and the other is that the same thread has two starting heads, such as M6XPN2 means that the thread of M6 has two starting heads, and the lead of this screw is equal to 2 times the pitch, so it can achieve fast screwing and fast exit.

The two ends of the threaded screws, the function is that the nut can be tightened at both ends when the screw is not moving. More flexibility.

There are many forms of double-ended screws (bolts, columns), and there are two kinds of screws in the same direction and in the opposite direction.

1.The effect of the rotation of the bice-head thread in the same direction:

1) Used in the main body for large equipment, need to install accessories, such as sight glass, mechanical seal seat, reducer frame, etc., this is the use of stud bolts, one end screwed into the main body, after installing the accessories with the other end of the nut, because the accessories are often disassembled, the thread will be worn or damaged, the use of stud bolts to replace will be very convenient.

2) When the thickness of the connector is very large and the length of the bolt is very long, the stud bolt will be used, which is more convenient to manufacture.

2.The rotation direction of the bice-head thread is opposite, and it is mainly used to connect the two components with relatively fixed positions, and the distance or tension between the two components can be adjusted simply and conveniently.

Double-ended screws are threaded at both ends and are used to connect the fixed link function of the machine. And what about double-ended screws? What is the national sock hole standard for double-ended screws? Let's take a look at what is a double-ended screw and the national standard for double-ended screws for your reference.

Studs are also called studs, and the two are the same thing.

In general, stud bolts.

There is no difference with a stud stud, it is the same thing, but some people call it a stud bolt, and some people call it a stud stud. Of course, the standard name should be called a double-ended stud.

There are three differences:1The bolt length of the stud bolt is larger than that of the stud bolt, and it is used for equipment with a large thickness of the connecting body.

2.Stud bolts are more widely used, such as connecting thick slabs and concrete roof trusses, roof beam hangers, monorail beam hangers, etc. 3.

Double-ended studs are mostly used in places with high pressure, high temperature and large temperature changes; Single-head type shoot bolts are used in general places.

The main uses of stud bolts are:

1. Used in the main body of large-scale equipment, it is necessary to install accessories, such as sight glasses, mechanical seal seats, reducer frames, etc., this is the use of stud bolts, one end is screwed into the main body, and the other end is equipped with a nut after installing the accessories, because the accessories are often disassembled, the thread will be worn or damaged, and it will be very convenient to replace the stud bolts.

2. When the thickness of the connecting body is very large and the bolt length is very long, stud bolts will be used!

3. It is used to connect thick plates and places where it is inconvenient to use hexagonal bolts, such as concrete roof trusses, roof beams, hanging monorail beams, etc.

What is a stud bolt: A stud bolt is generally called a stud stud, and a stud is a stud with threads at both ends and a smooth rod in the middle.

Thread: A spiral groove with an equidistant isocross-sectional profile machined on the outer surface of a cylinder or cone, or on the inner surface of a cylindrical or conical hole.

Screws: Threaded rods or taper rods with threads on the outer surface, with grooves at the top for the screwdriver to rotate or square heads for handlers to clamp.

Bolts: Refers to screws with larger diameters, which can also be without heads, such as stud bolts.

Nuts: Rings with threads on the inner surface of bolts or screws, or square cylinders or cylinders with round holes inside and square outside for handling and clamping, such as hexagon nuts and round nuts.

1. Due to its large thread rise angle (easy to slide), the friction formed by the screw and nut screwing is small, which is used to transmit power and movement.

2. The power is large, and there is basically no big loss in transmitting power.

3. Stable and firm transmission.
