The hexagon bolt is a precision fastener with a typical six-sided hex head. Known for their sturdiess and designed to be screwed in with a wrench or socket, hex head bolts can effectively transmit more torque than other types of bolts.
These bolts are carefully designed for high precision and strength, whether they are inserted into threaded holes or used together with hex bolts and nuts to clamp parts together. They play a vital role in mechanical assembly, ensuring that the parts are securely held together, and the hexagonal head provides the best tightening and loosening grip.
Working principle of hexagon bolt.
Hex bolts (including the popular M6 hex bolt) are essential in a wide range of industries, from automotive to construction. Its unique design allows it to withstand high torques and is ideal for heavy duty applications. Hexagon head bolts are also one of the only drive types that drive perpendicular to the threaded shaft rather than parallel to it, making them useful in situations where space is limited.
In use, hex bolts and nuts are usually combined in the machine to ensure a tight, firm fit. In scenarios such as automotive engines or building structures, hexagonal flange bolts provide the necessary clamping force to keep parts in place under pressure without the explicit use of washers.
Materials of hexagon head bolts.
At Accu, we pride ourselves on being able to offer a wide range of hexagon head bolt materials such as high strength steel, A2 and A4 stainless steel, brass and even nylon to meet any of your project needs.
High-strength steel hex bolts offer maximum strength and durability, making them ideal for heavy-duty applications. Stainless steel variants such as A2 and A4 have corrosion resistance, which is essential for outdoor or harsh environments. Lightweight materials such as nylon can be used for specific needs or corrosive environments where weight reduction is a priority.
Dimensions and types of hex bolts.
Accu's hexagon head bolt range is available in a wide range of thread sizes, from the small M2 hexagon bolt (2 mm) to the maximum size M36 (36 mm). They are also available in a variety of lengths, from an exact 3 mm to up to 200 mm, to suit every need.
Hex bolt types available include full thread, partial thread and special bolts such as hex flange bolts and seal hex bolts. But why stop there? We also have other finish options available, including pre-painted thread locks through our AccuLock series, and black hex bolts treated with our AccuBlack finish chemistry for a matte black finish.
The hexagon bolt size you choose will play a key role in determining its suitability for a particular application. If you need help at any time, please get in touch with our team of engineers who are more than happy to guide you through your project, even if you require custom manufacturing of specific components that we may not have listed.
Q: Why are the bolts hexagonal?
A: The hexagonal shape of the bolt is mainly for practical and efficient purposes. Hexagonal shapes strike an ideal balance between ease of manufacture and providing a large surface area for a wrench or socket. This shape allows for better torque transfer, reducing slip and wear during tightening or loosening.
Q: What is the difference between a hex screw and a hex bolt?
A: The main difference is that the head of the hex screw itself has a hex drive device, which is usually twisted with a hex wrench or hex wrench. The heads of hex screws come in various shapes and sizes. On the other hand, the head of the hex bolt is hexagonal, which is its main feature, and is designed to be twisted with a wrench or socket wrench.
Q: What is the difference between a stud and a hex bolt?
A: Stud bolts are headless fasteners, also known as threaded rods, that can be inserted into the workpiece to align and rest on it while being secured with nuts. However, hex bolts are usually used for general fastening purposes without additional alignment dimensions and provide shelving points.
Q: What are the advantages of hex bolts?
A: Hexagon bolt (including hexagon bolt and nut combination) is a necessary fastener, with high strength, easy installation, wide use and other characteristics, suitable for a variety of applications. The main advantages are high torque transfer and the ability to install with a wrench perpendicular to the threaded shaft.
Q: What tools are needed for hex bolts?
A: Usually, hex bolts use a wrench or socket wrench set, the size depends on the size of the hex bolt head, we choose from 4 mm to 55 mm.
Q: How do I know my hex bolt size?
A: To determine the dimensions of a hex bolt, measure the diameter and length of the threaded shaft. The diameter and height of the head are then measured. For specific types (such as M6 hexagon bolts), the thread size is indicated by the M number. Although length and head size may vary.
