High Strength Locking Firmware(such as high-strength bolts, high-strength nuts, etc.) are a type of fasteners designed to withstand large loads and harsh working conditions. Their main characteristics are as follows:
1. High material strength
Usually made of high-strength alloy steel, and heat treated to improve its tensile strength, yield strength and hardness.
Common strength grades include 8.8, 10.9, 12.9, etc. The larger the number, the higher the strength.
2. Strong locking performance
It has strong anti-loosening ability and is often used with locking washers, nylon locking nuts, metal locking nuts or coated with thread locking glue.
Some High Strength Locking Firmware use special structures to prevent loosening caused by vibration, etc.
3. Stable and reliable connection
It can maintain stable connection in high-load, high-vibration, and high-impact environments, and is widely used in machinery manufacturing, automobiles, bridges, construction, aerospace and other fields.
4. Good fatigue resistance and corrosion resistance
High Strength Locking Firmware usually need to be surface treated to enhance corrosion resistance.
The design and material selection should take into account its fatigue life to adapt to the alternating load environment.
5. High installation requirements
Special tools such as torque wrenches and hydraulic tensioners are required for installation to ensure that the preload meets the design requirements and avoid over-tightening or under-tightening.
There are also high requirements for the flatness of the installation surface and the accuracy of the hole position.
6. Poor reusability
Some High Strength Locking Firmware such as torsion shear bolts and glue-coated fasteners have reduced performance or weakened locking effect after use, and are not recommended for reuse.
