DIN 603 Refined Carriage Bolts - Grade 4.8 to 12.9 | China Suppliers & Factory提供高品质紧固件
Product introduction introduction
Generally speaking, bolts are used to connect two objects, usually through light holes, and need to be used in conjunction with nuts. They do not serve as a single connection. Tools usually use a wrench. The head is mostly hexagonal and generally larger. Carriage bolts are used in grooves, and the square neck is stuck in the groove during installation to prevent the bolt from rotating. Carriage bolts can move parallel in the groove. Due to the circular shape of the head of the carriage bolt, there is no design of a cross groove or an internal hexagon that can be used as an auxiliary tool, and it can also play a role in preventing theft during the actual connection process.
How to use carriage bolt use
Application scenarios of semi-circular head bolts
Half round head bolts are commonly used for hinged connections, including the following application scenarios:
- 1. Mechanical equipment connection. Half round head bolts are often used to connect components such as shafts and swing arms of mechanical equipment for articulated motion.
- 2. Structural connection. Half round head bolts can also be used for structural connections, especially in areas that require flexible connections, such as wall panels, ceilings, and doors and windows.
- 3. Transmission connection. Half round head bolts can also withstand transmission force, so they are used in the connection of transmission systems.
Advantages and disadvantages of semi-circular head bolts
Compared to ordinary bolts, half round head bolts have the following:
OUR Advantages Advantages
- 1. It can achieve hinged connection. The design of the head of the half round head bolt makes it easy to make hinged connections, which ordinary bolts cannot achieve.
- 2. Easy installation. Half round head bolts can be installed with just an appropriately sized pliers, without the need for special installation tools.
- 3. High strength. Compared with ordinary bolts of the same specification, half round head bolts have higher strength and can withstand larger loads.
However, half round head bolts also have some drawbacks:
- 1. Not easy to disassemble. Due to the special design of the head of the half round head bolt, special tools and techniques are required for disassembly.
- 2. The thread is prone to damage. The threaded part of the half round head bolt is prone to damage, which may limit its reusability.
Frequently Asked Questions FAQ
Q1: What is the main purpose of a carriage bolt?
A1: Carriage bolts are primarily used to connect two objects through light holes in combination with a nut. Their square neck design locks into a groove to prevent the bolt from rotating during installation.
Q2: How do carriage bolts prevent theft?
A2: Because the head of a carriage bolt is circular and lacks a cross groove or internal hexagon, it cannot be easily turned with standard tools, which provides an anti-theft function in actual connections.
Q3: Where are semi-circular head bolts typically applied?
A3: They are widely used in hinged connections for mechanical equipment (like shafts and swing arms), structural connections (such as wall panels, ceilings, doors, and windows), and transmission system connections.
Q4: What are the key benefits of semi-circular head bolts?
A4: They allow for easy hinged connections, can be installed simply with pliers without special tools, and offer higher strength and load capacity compared to standard bolts of the same size.
Q5: What are the limitations of using semi-circular head bolts?
A5: Their main drawbacks include being difficult to disassemble, requiring special tools and techniques, and having threads that are prone to damage, which can limit their reusability.
