22 Types of Screw Heads and Their Uses [with Pictures & Names]

Types of Screw Heads

A) Countersunk Screw Heads

Countersinking method are used for preventing the split of wood when the wood is drilled. By the help of countersinking both proper angle as well as pilot hold are created which is required for housing the screw. In this process the holes are pre drill in addition with correct head angle which helps in creating finish look. Due to the angle and shape of some screw heads they need countersinking.

Various shapes of head which are required to countersink before they are drilled are:

1. Flat Head Screw: ( Types of Screw Heads )

Flat Head Screw

Flat screw heads completely sit with the surface which leave no part of head exposed therefore these screws need to be countersink. The advantage of having flat screw head is that they do not stick out of the surface and leads catching other things on it. If the screw cover is used in this screw then the screw head are not visible.

2. Raised Head Screw: ( Types of Screw Heads )

Raised Head Screw

Raised head are also known as oval shaped head, and they have angle which is similar to that of flat screw but they have dome shaped head. Countersink is required for these screws for accommodating the angle. As compared to flat screw their head slightly come out of the surface. This shape does not help in drive performance of the screw.

3. Bugle Head Screw: ( Types of Screw Heads )

Bugle Head Screw

These types of screw heads are commonly used for the screws which are made for drywall and plasterboard. The shape of these screws is similar to flat screw head but under the surface of head it has an angle which helps in reducing the damage to the surface. Drilling of pilot holes are not required because they are self-drilling. Stress is distributed over a wider area as compared to flat screws because of their unique shape.

B) Non Countersunk Screw Heads

These screws have head shape without having an angle. Various types of non-countersink screw heads commonly used are:

1. Binding Head Screw: ( Types of Screw Heads )

Binding Head Screw

They are a unique screw which are used for various of projects. They have domed head and can screw in each other. Short binding screws are used for holding large manuals as well as book binding projects. They are also used for holding leather, swatches together.

2. Dome Head Screws: ( Types of Screw Heads )

Domed head screws are very common type of screw. They are best suited for the work in which head of the screw are not hidden like flat head screws. The dome shape head provide appealing design to the surface and the flat part behind the dome helps in stopping the screw where it is to be stopped.
