Application of stainless steel outer hexagon bolt Stainless steel outer hexagon bolt stainless steel usually refers to the steel which has the corrosion resistance to air, water, acid, alkali salt or other media. According to the different composition of the alloy, the stainless and acid resistance are emphasized respectively. Although some steels have rust resistance, [...]
How to prevent the outer hexagon bolt from breaking? The function of outer hexagon bolt is very important. Generally, it needs to be used with nut when tightening. The strength of different specifications and types of hexagon bolts is different. In order to prevent fracture in the process of use, there are some places to [...]
How to deal with the after-sale problems of high strength hexagon bolt? High strength hexagon bolt is made of high-strength steel. It is generally used in track, bridge and high-pressure equipment. In order to ensure its firmness, sometimes it needs to be prestressed before use. However, if the product has quality problems during use, it [...]
Heat treated high strength fastener should be quenched and tempered according to the technical requirements. The purpose of heat treatment and tempering is to improve the comprehensive mechanical properties of fasteners to meet the specified tensile strength and yield ratio of products. Heat treatment process has a vital impact on high-strength fasteners, especially its internal [...]

How to Choosing Hex Bolts Whether it’s finish, thread or size, the specification of hex bolt will depend on your needs. Design of Hex Bolts Stainless steel Stainless steel hex bolts aren’t just strong and resistant because of their finish. The entire body of the bolt is made from stainless steel. Stainless steel is corrosion [...]
What are the causes of stainless steel hexagon bolt rusting? How to avoid it? 1. The surface of stainless steel hexagon bolt adheres organic juice (such as melon and vegetable, noodle soup, phlegm, etc.) and forms organic acid under the condition of water and oxygen. The corrosion of organic acid on metal surface will rust [...]
Introduction to High strength external hexagon combination screw for buildings and workshops: High strength external hexagon combination bolt for steel structure is mainly used in railway and highway bridge, boiler steel structure, industrial workshop, high-rise civil building, tower and mast structure, hoisting machinery and steel structure where friction type high-strength bolt combination screw is required. [...]
What problems should be paid attention to when high strength steel structure bolts replace high strength bolts? 1) When the hole position is not correct, forced alignment will damage the thread of high strength bolt, resulting in the change of torque coefficient and pre tension. 2) It is possible that the internal stress in the [...]
The technological process of stainless steel hexagon bolt is as follows: 1. Normalizing: heat the stainless steel hexagon bolt to the appropriate temperature above the critical point AC3 or ACM, keep it for a certain time, and then cool it in the air to obtain pearlite structure. 2. Annealing: heating the hypoeutectoid stainless steel hexagon [...]
Identify High Strength Bolts is also skilled, generally in this industry for a long time, you will learn the skill, the following is for everyone to sort out some of the knowledge. 1. Identification: there are obvious strength grade marks on the package of bolts manufactured by regular manufacturers. Such as 8.8, 10.9 and 12.9. [...]
There are three kinds of Hexagonal bolt materials: carbon steel, stainless steel, copper. Carbon steel: We distinguish low carbon steel, medium carbon steel, high carbon steel and alloy steel by carbon content in carbon steel. 1. Low carbon steel C% ≤ 0.25% is usually called A3 steel in China. It is called 1008101510181022 in foreign [...]
The manufacturing process of stainless steel hexagon bolts is as follows: Normalizing: the screw is heated to the appropriate temperature above the critical point AC3 or ACM for a certain time and then cooled in air to obtain pearlite structure. Annealing: the hypoeutectoid screw is heated to 20-40 ℃ above AC3 and cooled slowly in [...]
Steel structure bolts are high strength bolts, and also kinds of standard parts. Good fastening performance, used in steel structure, engineering, so that the tightening effect. General steel structure, the requirements of steel structure bolt are 8.8 grade or above, there are 10.9 grade, 12.9 grade, all of them are high strength steel structure bolts, [...]
The Steel Structure Bolt thread refers to a kind of uniform helix bulge on the screw or bolt surface or the section of the internal surface, which mainly plays the role of connection, adjustment, transfer movement, etc. Generally speaking, the thread of steel structure bolt can be divided into three types according to the structural [...]
Bolt Classification Knowledge This time Fastener Bolt Exporter talks about bolt information other than threads. There are many types of bolts, and there are probably several classification methods: classification by the head of the bolt; classification by the material; classification by the performance level; classification by the connection force method. The first category is classified [...]
