Secure framing to metal where clearance is too tight for other rounded-head screws. Also known as panel clip screws, these have a slim pancake head that creates a nearly flush finish. The head’s flat underside makes more contact for a better hold on thin materials, such as sheet metal and plywood. Drill and fasten screws in one step using a Phillips driver. For more torque, you can also use a square driver.

Length is measured from under the head.
