DIN981/GB912/GB810 M95 Round Nuts

Made from Austenitic stainless steel, they contain about 18-20% chromium and 8-10% nickel, offering exceptional corrosion resistance and good machinability.In the chemical, petrochemical, and food processing industries, SS304 nuts are favored due to their corrosion resistance and hygiene properties. They are also widely used in medical devices, architectural decorations, and machinery.

DIN981/GB912/GB810 M95 Round Nuts are manufactured from 304 stainless steel, with a standard thread size of M95 . Their unique cylindrical design provides a larger contact area and enhanced anti-loosening capability, making them ideal for heavy-duty connection applications where high load capacity and reliable locking are required. These nuts comply with three major industrial standards — DIN 981 , GB 912 , and GB 810 , offering both international compatibility and conformity with domestic regulations.

Key Features
Material Advantages
Constructed from SS304 stainless steel , these nuts offer excellent corrosion resistance and oxidation resistance. They can operate stably in harsh environments such as humid or chemically aggressive conditions, maintaining their natural metallic luster without requiring additional plating.

Thread Design
A coarse thread profile is used, providing greater shear strength and facilitating faster, more efficient assembly. This design is especially suitable for high-strength connection requirements in large-scale equipment. The threads are unmarked (No Mark) , conforming to industrial-grade manufacturing specifications.

Mechanical Properties
With a rated tensile strength of 700 MPa , these nuts ensure structural integrity under high-load and high-vibration conditions, effectively minimizing the risk of deformation or fracture.

Application Scenarios
The M95 round nut is specifically designed for use in heavy machinery , large structural components (such as bridge supports and mining equipment), and marine engineering . Its cylindrical shape allows easy engagement with hook wrenches or specialized tools, making it particularly suitable for installations in confined spaces or where side-access installation is required. It serves as a highly reliable alternative to hexagonal nuts.

Standards & Compatibility
These nuts meet both German Industrial Standards (DIN 981) and Chinese National Standards (GB 912 / GB 810) , ensuring broad compatibility with bolts and studs of the same specification. This dual compliance supports global supply chain procurement and maintenance across multi-standard equipment systems.
