What are the different types of screw heads? A screw is a type of fastener, sometimes similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male thread (external thread) or just thread.
When choosing the right fastener for your application, you’ll need to consider several factors, including material, size, thread specification, and required torque.
The screw or bolt head is a key differentiating factor. Not only is the head the most recognizable part of the object, but its properties will also dictate the application advantages of the screw or bolt. Understanding the qualities of each head type will help you to decide which type is right for you.
Below are the most common types of bolt and screw heads, as well as their applications:
Pan head: A low disc with a rounded, high outer edge with large surface area. Pan heads are one of the most popular head types, recommended for most new designs to replace round, truss, or binding heads.

Button or dome head: Cylindrical with a rounded top
 |
 |
 |
Round head: A dome-shaped head used for decoration
 |
||
Mushroom or Truss head: Lower-profile dome designed to prevent tampering
 |
 |
|
Countersunk or flat head: Conical, with flat outer face and tapering inner face allowing it to sink into the material. The angle of the screw is measured as the full angle of the cone.
 |
 |
 |
Oval or raised head: A decorative screw head with a countersunk bottom and rounded top. Also known as “raised countersunk” (UK)
 |
||
Bugle head: Similar to countersunk, but there is a smooth progression from the shank to the angle of the head, similar to the bell of a bugle
 |
|
 |
Cheese head: Disc with cylindrical outer edge, height approximately half the head diameter
 |
 |
 |
Fillister head: Cylindrical, but with a slightly convex top surface. Height to diameter ratio is larger than cheese head.
 |
||
Flanged head: A flanged head can be any of the above head styles (except the countersunk styles) with the addition of an integrated flange at the base of the head. This eliminates the need for a flat washer.

Binding Head: Binding heads are another model that have been replaced largely by pan heads. However, the medium-low head and undercut beneath it bind wires and eliminate fraying, making this type suitable for electrical and radio work.
