NATO Supply Class 5310 is a classification within NATO Supply Group 53, which is dedicated to Hardware And Abrasives. Specifically, Class 5310 pertains to Nuts And Washers.
Nuts and washers are essential components in various mechanical and construction applications. They are used to secure and fasten different parts together, providing stability and preventing loosening or disassembly.
In the NATO supply system, Class 5310 includes a wide range of nuts and washers, such as:
1. Nuts: These are typically hexagonal or square-shaped metal fasteners with a threaded hole in the center. Nuts are used in conjunction with bolts or screws to create a secure joint. They come in various sizes, materials, and thread types to accommodate different applications.
2. Washers: Washers are flat, thin discs with a hole in the center. They are placed between the nut and the surface being fastened to distribute the load and prevent damage to the surface. Washers can also be used to provide insulation, reduce friction, or act as spacers.
NATO Supply Class 5310 ensures that the nuts and washers meet specific quality and performance standards required by NATO member countries. These standards may include factors such as material composition, strength, corrosion resistance, and dimensional specifications.
When procuring nuts and washers within NATO Supply Class 5310, it is important to consider the specific requirements of the application, such as the type of material being fastened, the load-bearing capacity needed, and any environmental factors that may affect the performance of the fasteners.
Overall, NATO Supply Class 5310 plays a crucial role in ensuring the availability of high-quality nuts and washers for military and defense-related applications within NATO member countries.
Includes Locknuts; Eye Nuts; Plain Nuts; Castellated Nuts; Wing Nuts; Plate Nuts; Push on Nuts; Concave and Convex Washers; Flat Washers; Keyed Washers; Lock Washers; Shouldered Washers; Split Washers.
Excludes Bearing Thrust Washers (FSC 3120); Shims (FSC 5365); Ring Spacers (FSC 5365); Plate Spacers (FSC 5365); Lock Rings (FSC 5365).
