Hexagon Nuts & Hexagon Bolts
Hexagon nuts and hexagon bolts are probably the most common type of fasteners, they’re used everywhere.
The reason they’re so popular is because the hexagon shape of the head is very versatile, it can be grabbed by tools from all angles and even by hand if need be.
Hexagon nuts use their shape to their advantage. They’re easy to tighten and loosen thanks to their 6 sides, and you can access them from 360 degrees providing there’s space to move your tools.
These hexagon nuts have been around for a long time, they were first documented around the 1700s and they’ve been used ever since.
The same applies to hexagon bolts, they’re easy to tighten and loosen because of their shape.
The reason they’re hexagon nuts and hexagon bolts and not pentagon or octagon is because the side 6 of a hexagon give enough faces for a tool to grip, but not so many that it’s easily rounded off through use over time. Inevitably the hexagon nuts and bolts will lose some of their shape over time but not having too many sides gives them the best possibly chance of lasting longer.
Non-Standard Socket Screws
In a contrast to hexagon nuts and bolts there’s also socket screws / non-standard socket screws.
Non-standard socket screws have a round head, with a hexagon inset in the top of the head. These screws are made to be used with an Allen key and not gripped by the head. Non-standard socket screws differ from standard socket screws by being different shapes and sizes.
Socket screws and non-standard socket screws are used in many different industries, and you tend to find them in a lot of self assembly furniture and on bicycles as well as many other things.
Hague Fasteners are specialist fastener manufacturers, they manufacture and distribute non-standard fasteners.
