Hex Bolt Description

Hex bolts have hexagonal heads and machine threads for use with a nut or in a tapped hole. Also known as hex cap screws or machine bolts.

A hex head cap screw is a six-sided bolt with a trimmed hex head and a washer face on the bearing surface. ... Hex cap screws are commonly used in OEM applications where precise tolerances are needed.

Hex bolts are six-sided bolts made of carbon steel,stainless steel, alloy steel and frequently used in construction and repair applications. A few of the most common specifications include: ASTM A307A, A354, and F1554. Hex bolts can be partially threaded or fully threaded, which are more commonly referred to as a tap bolt.

Hex bolts can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. Hex bolts with forged heads are also commonly used as headed anchor bolts.


What is the hexagon bolt (hex bolt)
  
Outer hexagon bolts can be called hexagon bolts or outer hexagon screws, or outer hexagon screws. In general, hexagon bolts can be divided into the following types: ordinary bolt A, ordinary bolt B, ordinary bolt C. Ordinary bolt A and ordinary bolt B are refined bolts, under normal circumstances, they are rarely used in daily life. Ordinary bolt C is commonly used in daily life. For example, in some work that needs to be temporarily connected or needs to be disassembled, C-level ordinary bolts are often used.   
The material of high-strength hexagon bolts is different from that of ordinary hexagon bolts. High-strength hexagon bolts are generally used for permanent connection work. In construction projects, the main bolt connections required by the structure are generally connected by high-strength hexagonal bolts.

What is the difference between a hex bolt and a hex cap screw?

A hex cap screw has tighter tolerances on the body dimensions and features a chamfered end and a washer face under the bolt head. A hex cap screw is often called a finished hex bolt. Hex bolts have a flat end and lack the washer face under the head.

Black hex bolts Made of carbon steel material, black oxidation treatment, hex head, left hand reverse thread design. Fixed components, industrial and construction fasteners. To tighten the reverse screw, turn counterclockwise. To loosen the reverse screw, turn clockwise.


Hexagon bolt standard

The standard for hexagon bolts stipulates that the thread specification is M3-M64. Among the hexagon bolts A and B, grade A is used for bolts with D<=24 and L<=10D, or L<=150mm, while grade B is used for D>24, or L>10D, or L>150 bolts. The specification of the hexagon bolt is D=M (thread diameter), the nominal length is L=mm (length), and the performance grade of the hexagon bolt is 8.8. Hexagon bolts are the most frequently used type of bolts in daily life. The main function of the external thread of the hexagon bolts is to cooperate with the nut. This method of thread connection can make the two The parts are combined.
Among them, the stainless steel outer hexagonal bolts are mostly full-thread with the same hexagonal head. The full-thread bolt standards are DIN933, GB5783, ISO4017, ANSIB18.2.1, JISB1180, and the non-full-thread bolt standards are DIN931, GB5782, ISO4014, ANSIB18.2.1. , JISB1180. There are 4.8 and 8.8 grades for the standard of hexagon bolts. Grade 4.8 outer hexagon bolts are cheaper than grade 8.8 outer hexagon bolts and have a wider range of uses. However, the hardness of the 8.8-level external hexagon bolt is greater, and the product will appear more safe and stable in use.
