Hex Head Machine Screws

Hex Head Machine Screws

Hex head machine screws have a finer thread and are designed to be threaded into a pre-tapped hole or used with a nut. They are often used in applications where components need to be fastened together with a flush surface, such as in machinery, appliances, and electronic equipment.
The heads of hex head machine screws are smaller and more compact compared to bolts, as they are designed to fit into tight spaces and provide a flush finish when tightened.

Hex head machine screws are available in standard sizes, but they may have more limited options compared to bolts due to their specific application. Sizes range from #2 to ½”.
