Certain things like bikes, cars, and furniture use hexagonal bolts for fastening. Hex bolts can only be used with the right diameter key and they don’t slip like Phillips and Flatheads. Also, the hexagonal tip keeps bolts from falling so you don’t need a magnet to hold your fasteners. Furthermore, it’s easy to identify which Allen key you need for each fastener, and you can use ballpoint hex keys if you need to work at an angle.
Since the hex bolt design is so practical, why don’t we use this type of fastener for everything? Why don’t we see hex wood screws and hex drywall screws ?
Edit : I’m asking about fasteners in general (like screws, bolts, etc)
In: Engineering
Almost everything in life comes down to cost.
If company orders ten million Phillips head screws to make their product and it costs 100,000 dollars. A hex key bolt may be a few Penny’s more each which can average to tens of thousands of hundreds of thousands .
I’ll add why use hex when torx is superior to hex and normal screws like Philips.
