With a point “like a drill bit”, these screws create their own hole, and their own thread in one action. This is probably where the confusion with self-tappers comes in – both kinds of screws are technically self-tapping as far as the function of their threads are concerned, but the massive difference is in the function of their points.Self-drillers are also commonly called ‘Tek’ screws, a proprietary brand name associated with their unique shape and function.
