Countersunk Threaded Hole at Madeline Hardwicke blog

Countersunk Threaded Hole. A countersink is a conical hole (cut) or conical depression (form) created in a material around a hole. For ansi/imperial fasteners, it is commonly at 82°, 90° for metric fasteners, 100°. Countersunk holes are used for applications where a countersunk bolt or screw is required. A countersink is an angled taper applied to a hole that allows a fastener (usually a flat head screw or similar) to sit even with, or below the surface which has been countersunk. The purpose of chamfering or countersinking an internal threaded hole is typically to avoid creating a raised burr that can prevent a mating part from properly seating with. The ‘conical’ element differentiates a countersink from a counterbore, which has a flat bottom. A countersink hole is one in which the outer edge of the hole has been opened up to a conical entry. Below are visuals of countersinking and counterboring in cutting and forming applications. A countersink hole is a conical hole cut into a material to allow the head of a countersunk fastener, such as a screw or bolt, to sit flush. A countersink consists of a conical hole that is coaxial to a cylindrical hole, where the angle of the cone is determined by the fastener to be used. Like counterbore holes, countersink holes ensure the bolt or screw sit below the surface.
