Sleeves and Nuts

Sleeves are cylindrical components that provide a protective or supportive layer between parts, often used to reduce friction, protect surfaces, or ensure proper alignment. They can also act as spacers or insulators. 

Nuts are fasteners with a hexagonal or other shaped hole that fits onto a bolt or screw to secure components together. They come in various types, such as standard hex nuts, lock nuts, and wing nuts, depending on the application.

Sleeves and nuts are essential in assembling and maintaining machinery, automotive, and various other systems.
