eli5: Why are there different types of screwnail heads? Does it really affect the strength or integrity of the screw if the head is a Phillips, Robinson or standard?
In: Engineering
Yes, there are differences in torque, wear, and failure modes. Slots provide a lot of torque, but can slip out and harm the product. Phillips cam out under torque, so they are less likely to slip. Torx and other fancy styles have higher torque without cam out, but they can wear more quickly. Exotic fasteners serve to make it harder for users to get inside and mess things up, the options are endless.
