Understanding the Hardness of Metal Fasteners
The hardness of a metal fastener (such as screws, bolts, nuts, and rivets) is a critical mechanical property that defines its resistance to permanent deformation, wear, abrasion, and indentation. Essentially, it indicates how well the fastener can maintain its shape and function under load and in challenging environments. 1. Why Hardness Matters Prevents Thread Galling: Harder […]

Here, the metal is cooled very quickly. Different mediums can be used to cool at different speeds, such as water, air, or oil.
