These button head screws have a shiny look and won't rust in damp environments. Made of brass, they're also conductive and nonmagnetic, making them useful for electrical applications. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
Length is measured from under the head.
