High-Strength Class 10.9 Steel Screws Application Solutions

High-Strength Metric Class 10.9 Steel Screws Application Industry Solutions

Critical features of High-Strength Metric Class 10.9 Steel Hex Head Screws include ease of construction, good stress performance, removability, fatigue resistance, and no loosening under dynamic loading. These features make High-Strength Metric Class 10.9 Steel Hex Head Screws a promising connection method. Specifically, the advantages of High-Strength Metric Class 10.9 Steel Hex Head Screws are as follows:

1. Simple construction: High-Strength Metric Class 10.9 Steel Hex Head Screws are relatively simple to connect by applying pre-tension P to create frictional resistance between the connected parts to withstand the external load; this connection does not require a complex construction process.

2. Good stressing performance: High-Strength Metric Class 10.9 Steel Hex Head Screws are stressed firstly by applying a pre-tensioning force inside them and then by generating frictional resistance on the contact surfaces between the connected parts to withstand external loads. This design gives High-Strength Metric Class 10.9 Steel Hex Head Screws excellent load-bearing properties.

3. Removable and Replaceable: High-Strength Metric Class 10.9 Steel Hex Head Screws can be easily replaced when needed without disturbing the surrounding bolted connections.

4. Fatigue Resistant: High-Strength Metric Class 10.9 Steel Hex Head Screws have excellent fatigue resistance and can maintain stable performance over long periods.

5. No loosening under dynamic loading: Even under dynamic loading, High-Strength Metric Class 10.9 Steel Hex Head Screws can maintain a good connection without loosening.

High-Strength Metric Class 10.9 Steel Hex Head Screws: Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. Dimensions meet ISO (formerly DIN) or DIN specifications. Length is measured from under the head.

Steel screws should be used in dry, noncorrosive environments. Zinc yellow-chromate plated and zinc-plated steel screws resist corrosion in wet environments. Blue-dyed screws are easy to distinguish. Black corrosion-resistant coated steel screws resist chemicals and withstand 1,000 hours of salt spray. To maintain corrosion resistance, use these screws with black ultra-corrosion-resistant-coated nuts and washers.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws: Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Black-phosphate steel screws are mildly corrosion-resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.

Screws that meet ISO 898-1 or SAE J1199 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.2.3.9M or DIN 6921 comply with specifications for dimensional standards.

Alloy Steel Button Head Torx Screws: Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Torx-Plus screws can be used with both Torx-Plus and Torx tools. Length is measured from under the head.

Black-oxide alloy steel screws are mildly corrosion-resistant in dry environments.

Zinc-plated alloy steel screws resist corrosion in wet environments.

In addition, the application of high-strength bolts also has the following characteristics:

- With friction type High-Strength Metric Class 10.9 Steel Hex Head Screws connection, the force is transmitted by friction on the surface of the steel plate, which has a large area of transmitted force and concentrated stress and can effectively improve the fatigue strength of the member.

- High load carrying capacity: the load carrying capacity is about 18% higher than rivets. Under the same force, the number of High-Strength Metric Class 10.9 Steel Hex Head Screws is relatively less than the number of rivets, so the geometry of the node spliced plate is small, which can save steel.

- Convenient construction, as long as after simple training, can be on-the-job operation.

The steel structure is not easy to loosen during transportation, which reduces the maintenance workload. It can also be replaced if loosening occurs.

- Construction conditions are good. The bolt hole can be molded in the factory, eliminating the need for a second reaming process.

These features make High-Strength Metric Class 10.9 Steel Hex Head Screws widely used in construction, bridge, machinery, and other fields.

High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws Grade and Its Properties

High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws are screws that can withstand more excellent tensile and shear forces and are widely used in mechanical connectors. Common high-strength screw grade 8.8, 10.9, 12.9, etc., where the number indicates the percentage of tensile strength and shear strength ratio of the screw. For example, a grade 8.8 screw suggests that it has a tensile strength of 8 times and a shear strength of 0.8 times. The following are the main characteristics of each grade:

1. Grade 8.8 screws: with a tensile strength of 800 N/mm², they are suitable for general mechanical connections, general construction, and equipment.

2. 10.9-grade screws: tensile strength of 1000N/mm², suitable for mechanical equipment requiring high strength and durability, such as automobiles, locomotives, airplanes, and so on.

3. 12.9-grade screws: tensile strength of 1200N/mm², suitable for mechanical connections requiring higher load capacity, such as significant construction machinery, motorcycle engines, etc.
