An in-depth study of hexagonal bolts

Good day! Do you know Hex Bolt? The hexagon bolt is a fastener consisting of a head and a screw. ‌ It is divided into two kinds of outer hex bolt and inner hex screw, mainly used for fastening mechanical equipment. According to the use and performance requirements of bolts, hexagonal bolts can be further subdivided into outer hexagonal bolts and inner hexagonal screws. Hexagon head bolts can be divided into ordinary bolts and those with hinged holes according to the force mode of connection. The bolts used for reaming holes need to match the size of the holes and are mainly used to withstand transverse forces. According to the shape of the head, hexagonal head bolts also include hexagonal head, round head, square head, and countersunk types, of which countersunk head bolts are often used in places where the surface of the connection is smooth without protrusions. In addition, in order to meet the needs of locking after installation, the hexagonal head bolt is also designed with holes in the head and holes in the rod part, which can make the bolt not easy to loose when subjected to vibration.

Q1: What are the materials of hex bolts?

There are generally two kinds, one is iron, that is, carbon steel. One is stainless steel, of course, there are copper, aluminum, brass nuts, but these are less used. Copper is more or less useful, like aluminum bolts are rarely used. 

Q2: What’s the advantage of hex bolt?

• Design Diversity ‌: There are many kinds of head shapes of hexagonal bolts, including hexagonal head, round head, square and so on, to meet different installation needs. For example, countersunk heads are designed where smooth surfaces are required without protrusions, while square head bolts are suitable for situations where large tightening forces are required.‌
• Convenience Of Use ‌: The use of hex bolts is very convenient, whether it is the outer hex or the inner hex design, there is a corresponding sleeve to match it, easy to install and disassemble quickly. The outer hexagon bolt has good self-locking and large pre-tightening contact area, which can withstand large pre-tightening force, while the inner hexagon bolt is more suitable for use in narrow space, maintaining the smooth and beautiful surface of the workpiece.
• Carrying Capacity ‌: hexagonal bolts have a large force surface and can withstand greater loads, especially when the position of parts needs to be fixed and shear caused by transverse forces is borne.
• Safety ‌: The design of hexagonal bolt takes into account the use in the vibration environment, through the head or rod part of the hole position, to prevent the bolt in the vibration environment to loose, improve the safety of use.‌

Q3: I can't find the exact size of the hex bolt I want! This is not a common size!

Absolutely no problem for Wuxi Sun! You can find the most common sizes from us! For unique sizes, we will customize them according to your sizes or drawings, as we handle in many cases. Small size or large size is no problem for us! We will also provide professional advice and considerate service!

Q4: Any notes if i designed my own hex bolt?

A5: For custom services, the higher the quantity, the better the price. For special shaped hex bolts, there will be mold costs. If the quantity is sufficient, the mold cost will be reduced.
