Product Description
Product Overview
This product is a stainless steel hexagonal thickened nut complying with GB6175 standard, manufactured from 304 stainless steel. Compared with standard hexagonal nuts, its thickness is significantly increased, thereby providing a larger bearing area and thread engagement length, and significantly improving the load-bearing capacity, tensile strength and anti-loosening performance of the connection. The 304 stainless steel material ensures that the product has excellent corrosion resistance in most environments, suitable for fastening occasions that require high load-bearing and corrosion resistance.
Core Advantages
-
Stronger Load-Bearing Capacity: The thickened design increases the force-bearing cross-section and thread contact length, greatly improving tensile and shear strength.
-
Excellent Anti-Loosening Performance: The larger thickness and engagement length enhance the self-locking performance of the thread pair, effectively resisting loosening caused by vibration.
-
Excellent Corrosion Resistance: 304 stainless steel material provides good corrosion resistance to atmosphere, water and various chemical media.
-
High Reliability and Long Service Life: The combination of high strength and corrosion resistance ensures long-term reliable connection under harsh working conditions.

Warm Tips
-
It is recommended to use a torque wrench during installation and tighten according to the torque value specified in relevant standards or design requirements to ensure the expected preload is achieved.
-
When stainless steel is in contact with certain metals (such as carbon steel), electrochemical corrosion may occur in a humid environment; it is recommended to take insulation measures.
-
When used in high-temperature environments (it is recommended that the long-term service temperature be lower than 400℃) or specific chemical environments, please evaluate the material applicability.
