What is a Sleeve Nut?

A Sleeve Nut (NUT,SLEEVE) is an internally threaded item with a cylindrical and/or square, hexagonal, octagonal, or dodecagonal outer periphery (parallel to the threaded axis) a portion(s) of which may or may not be enlarged, forming a flange(s) and/or shoulder(s). Items not having an enlarged outer portion may be threaded, a part of the full length, or tapped from both ends. Items having an enlarged outer portion (flange(s) or shoulder(s)) may be threaded the full length, threaded a part of the full length, or tapped from both ends. Items tapped from both ends shall have either right-hand threads on both ends or left-hand threads on both ends. For items conforming to any of the above and having a length overall exceeding two times the largest outside diameter or width across flats, use POST, ELECTRICAL-MECHANICAL EQUIPMENT. For items with an outside contour that is the same the full length, having a continuous thread through its entire length, and the length does not exceed two times the diameter or width across the flats use NUT (1), PLAIN (as modified).

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.
