2. The main characteristics of the product
High-quality 304 stainless steel material: 304 stainless steel is selected, which has good corrosion resistance and can maintain stable performance in many harsh environments such as humidity, acid and alkali, etc. It is not easy to rust and can effectively prolong the service life, which is suitable for outdoor facilities, kitchen equipments, bathroom fixtures, etc. with high requirements for rust prevention, ensuring long-term reliability of the connected parts and reducing maintenance costs and connection failure problems caused by rusting.
Full thread design: The screw part adopts full thread structure, which increases the engagement length of the threads, and can provide more stable and even fastening force between the connected parts of different thicknesses, and improve the reliability and loosening resistance of the connection. Whether it is a thin plate connection or a thick plate fixing, it can achieve a tight and solid connection effect, enhancing the stability and safety of the overall structure.
Precise size specification: M12 to M24 multiple specifications to meet the needs of different sizes of connections, to ensure precise matching with various nuts, studs and connected parts, whether small precision instruments or large industrial equipment fastening, you can find the right specifications, convenient for users to choose according to actual needs, improve installation efficiency and connection quality, to achieve accurate and reliable fastening effect.
Hexagonal head design: the head adopts hexagonal design, which is convenient for tightening operations with tools such as spanners or sockets, and can provide a larger tightening torque to ensure that the bolts can achieve the required degree of tightening during installation, and the shape of the hexagonal head is also convenient for operations in narrow spaces or multi-angle positions, which improves the convenience and flexibility of the installation, and reduces the difficulty of the installation and the intensity of the work.
3. Product use scene
Industrial manufacturing and equipment maintenance: in the manufacturing process of various types of industrial machinery and equipment, such as machine tools, printing presses, textile machinery, etc., used to fix the key components and connect the structural components, its high strength and reliable fastening performance can ensure that the equipment in high-speed operation, severe vibration conditions, the connection between the components is firm and reliable, to avoid equipment failure and safety accidents caused by loose bolts, improve the overall performance of equipment and reliability, extend the service life of equipment, reduce the number of repairs and costs to protect the continuity and stability of production. It improves the overall performance and reliability of the equipment, prolongs the service life of the equipment, reduces the number of maintenance and cost, and guarantees the continuity and stability of production.
Architectural and structural engineering: widely used in the erection of architectural steel structures, the construction of bridge projects and the connection of pre-embedded parts in concrete structures. In these large-scale architectural and structural projects, hexagonal bolts are able to withstand great tension and pressure to ensure the stability and safety of the structure. At the same time, its corrosion resistance is essential to protect the structural integrity of the long-term use process, effectively preventing rust and loosening of bolts caused by wind, rain, sun and other factors, providing a reliable guarantee for the safety of buildings and infrastructure to reduce the structural damage caused by casualties and economic losses.
Automotive and Transportation Industry: In the assembly and repair of automotive engines, chassis, bodies and other components, it is used to connect key parts to ensure the safety and reliability of automobiles in the process of driving. Its all-thread design and precise size specifications can meet the strict requirements of automobile manufacturing on the precision and strength of parts connection, preventing parts from falling off or being damaged due to loosening of bolts, and safeguarding the lives of drivers and passengers, and it is also applicable to the manufacturing and maintenance of trains, ships, aircraft and other means of transport to provide strong support for the development of the transport industry.
4. Product use instructions
Preparation before installation:
Check the appearance of the bolt for cracks, deformation, thread damage and other defects to ensure that the product quality is intact. At the same time, check whether the supporting nuts, washers and other accessories are complete and appropriate specifications, if any problems with timely replacement, so as not to affect the installation effect.
According to the material, thickness and connection requirements of the connected parts, select the appropriate specifications of the bolt, and determine the corresponding tightening torque, general product manuals or relevant standards will provide reference values, be sure to strictly follow, to avoid improper tightening torque caused by connection problems.
Use cleaning cloth or appropriate solvent to clean the threaded holes of the connected parts and the threaded part of the bolts, remove oil, rust, dust and other impurities to ensure good engagement of the threads and enhance the reliability of the connection and fastening performance.
Installation steps:
Pass the screw of the bolt through the mounting hole of the connected part, make sure that the hexagonal surface of the head of the bolt fits closely with the surface of the part and is flat without skewing, add washers to adjust the gap or increase the friction if necessary.
Screw in the matching nut on the screw, use the appropriate tools (such as spanners, torque wrenches) according to the specified tightening torque to gradually tighten the nut, uniform application of force, to avoid unilateral uneven force, for a number of bolts connected, should be tightened according to the order of the diagonal or cross to ensure that the connection is uniformly tight.
In the process of tightening, pay attention to observe the connection of the connected parts, if there is a gap or uneven phenomenon, you can adjust the position of the bolt or add a washer to correct, to ensure that the connection is tightly fitted, no loosening or displacement.
Precautions for use:
In the process of use, regularly check the bolt connection status, to see whether there are signs of loosening, deformation, corrosion, especially after the equipment is subjected to vibration, temperature changes or long-term use, such as loosening should be promptly re-tightened according to the specified torque, and corrosion damage is found in a timely manner to replace, to ensure that the connection is safe and reliable.
Avoid bolts to withstand excessive external impact or overload, to prevent fracture or damage to the connected parts, in the design and use of the full consideration of the bolt bearing capacity, a reasonable choice of specifications and connection to ensure that the use of the normal operating range.
If it is necessary to dismantle the bolts, use suitable tools to loosen the nuts step by step in the reverse order of installation, avoid forcible dismantling resulting in thread damage or deformation of the parts, and after dismantling, keep the bolts and accessories in a proper way for subsequent use or inspection and maintenance.
