Description:
The Philips drive has a x-slot that allows the use of a Philips driver.
The flat head is conical for use in countersunk holes, and the flat top is flush with the mating surface.
Machine screws can be used with nuts or directly screwed into the receptacles with screws to secure metal parts.
To get the length of the fastener, it is measured from the bottom of the head to the tip of the screw.
If you need a nut, use the nut of the same finish and use screws for proper installation.
