These are ideal for projects that don’t require you to hide the head of the screw like you would with a flat head, such as with an ottoman using decorative screws that protrude from the fabric. Domed Headsĭomed heads are one of the most common types you’ll find.
#NAMES OF WEIRD SHAPES MANUALS#
Often, short binding screws can hold together large manuals and other bookbinding projects, but you can also use them to hold together swatches, leather, and more. These screws have a slightly domed head and screw into each other with a male and female side. Binding Headsīinding screws are a unique type of screw that you can use for a range of projects. This shape is much like a flat screw head, except that, instead of an angle underneath the surface of the head, you’ll see a curved shape that can reduce damage to a surface.īugle screws are self-drilling, so you won’t need to drill any pilot holes before using them, and their unique shape allows them to distribute stress over a wider surface than flat screws. Bugle Headsīugle heads are used mainly on screws made for plasterboard and drywall. This shape doesn’t necessarily help the screw’s drive performance, but it, instead, is more for decoration. Unlike a flat screw, the head of a raised screw will come out of the surface slightly. You’ll also need to countersink these screws to accommodate the angle. Raised heads, sometimes known as oval-shaped heads, have an angle much like flat screws but have more of a dome-shaped head. This head shape helps give the screw a longer thread on the same screw length because of its shorter head size. A flat undercut 82-degree head has the same angle as a standard 82-degree head, but the head is much shorter. A higher degree requires a shorter, but more spread-out, countersink hole. An 82-degree flat head is the standard angle, but there are also 90-degrees, 100-degrees, and more. The degree of a flat head refers to its head angle or the angle from the top of the head to the surface where the threaded part meets the head. You also won’t see the screw head if you use a screw cover. The benefit of flat screws is that you won’t have to worry about your screw sticking out from the surface and causing other things to catch on it, which is essential if you’re creating your own sofa or building a bookshelf that people will walk by often. These types of screws require you to countersink them. Here is the list of different types of Screw heads:įlat screw heads sit entirely flush with a surface, leaving none of the heads exposed. Of the many that exist, the most common are: slotted, Phillips, combination (both slotted and Phillips), hex, socket, square, Torx®, and wrenches.
#NAMES OF WEIRD SHAPES INSTALL#
The drive style - or what is known as the drive recess - refers to the type of tool you use to install (or remove) the screw. Manufactured from plastic, these caps are available in standard colors to match commonly used plastic laminates and wood.īugle heads are commonly found in drywall screws, and the head design automatically compresses the drywall paper and plaster as it is installed, creating its own countersunk hole. If you use flat head screws in finishing, consider using a flat head screw cover (aka “beauty cap”) to hide the head (not all drive types accept screw covers). The advantage is that little or no part of the head protrudes above the surface of the material. Unless the material is very soft, flat and oval heads require a countersunk hole. Sometimes features are combined, as in the case of slotted hex, hex washer, slotted hex washer, and round washer head designs.Ĭountersunk designs consist primarily of flat, oval, and bugle heads. This style includes binding, button, cheese, fillister, flange, hex, pan, round, socket, and low socket, square, and truss heads (binding head is sometimes referred to as binder head). Non-countersunk heads – where the head is completely exposed comprise the widest variety. There are two basic designs: countersunk and non-countersunk. The drive recess or style is ultimately based on the tool you use during installation. Your chosen head shape or style can either serve a functional or decorative purpose. The two basic types of screw heads, countersunk and non-countersunk, include various unique designs.
