Binder / Binder Undercut - Often used for electrical applications. The undercut area beneath the head allows space for wire connections.

Bugle Head - These are flat-headed screws, but with a more curved neck. It can sink into the drywall easily without tearing into the paper surface.

Button Head - Button head types have cylindrical heads with curved tops and flat bearing surfaces. They slightly protrude out of the workpiece and are used for aesthetic purposes. They are the most common is socket driven screws but are also becoming more popular with six-lobe style drives

Fillister Head - The screws has the smallest head diameter to get into the machine screw. It is designed to deliver maximum power by combining the head height with its diameter.

Flat Head (82 degrees) - It is made to countersunk in a hole with its angled shape under the head by providing a flush surface.This head is designed to sit flush with the surface of the material it is binding. A characteristic of flat head screws is the cone-shaped bearing surface under the head. The general angle of this bevel is 82° in the Unified System (U.S.A.) and 90° in the Metric System (Most other countries of the world).

Flat Undercut Head (82 degrees) - It is used instead of the standard flat head for short sizes. Allows shallow countersinking than standard 82 degree flat heads. This head is designed to sit flush with the surface of the material it is binding. A characteristic of flat head screws is the cone-shaped bearing surface under the head, which in this case in undercut allowing for more threading of short length screws.

Flat 100 Head - It uses a 100-degree angle instead of a standard 82-degree angle. These are also used for thinner materials that need a flat head.

Flat 100 Undercut Head - These are used instead of flat 100 for short screws that allow longer grip.

Flat Head (Metric) - It has a 90-degree head angle and comes with a metric flat head.

Hex Head - This classic head style features a six sides and a flat top of the head, which is the most common head in all fasteners. It can be tightened with almost any wrench of the correct size.It allows for greater torque.

Hex Washer Head - It is similar to hex with 6 flat sides and a washer face to provide a large bearing surface. It creates a larger surface connection area. The head and washer are usually combined into a single unit or there is a free floating washer directly below the head. Both of these spread out clamping force of the fastener on the joint. This fastener head is very similar to a hex flange head. There is often a secondary drive, a slot or Philips, in the head of this screw.

Modified Truss Head / K Lath - It is the combination of a round head and a one-piece washer for a large/profile bearing surface.The rounded head top is much lower and flatter while the width of the head is wider, than pan or round screws of the same nominal size. The modified truss is basically a truss with an extra flange around the outside of it to increase bearing force.

Oval Head - It is similar to the flathead, but are angled under the head for easy countersinking in a hole. It provides a more finished appearance as its rounded top sits above the surface when installed.Also known as the raised counter sunk head, this style has the signature conical bearing surface characteristic of flat head screws. However, the head is raised allowing a deeper drive slot for more driving force.

Oval Undercut Head - The screws are used in shorter screw lengths that allow longer thread grip for more countersinking. Also known as the raised counter sunk head, this style has the signature conical bearing surface characteristic of flat head screws. However, the head is raised allowing a deeper drive slot for more driving force. The undercut head is cut to 70% of the normal head height.

Pan Head - These are multi-purpose screws with moderate head height and diameter. This general purpose head has a flat bearing surface with a short disc-like body and a slightly rounded top surface. Can be used in most situations when general bearing strength is needed.

Round Head - The screws are similar to pan head, but have a thicker round head for a more finished appearance. This dome head has a flat bearing surface and has general bearing strength. It is preferred in situations of aesthetics for its smooth appearance.

Round Washer Head - The screws with the bearing surface is for situations where the round head is needed. It has a similar style to that of the modified truss head style.This dome head has a flat bearing surface and has general bearing strength. It is preferred in situations of aesthetics for its smooth appearance. This style has a flange around the outside similar to a washer to increase bearing force.

Serrated - The head and washer are usually combined into a single unit, which spreads out clamping force of the fastener on the joint. This style also has radial ridges on the underside of the washer to increase locking force of the head. This fastener head is very similar to a hex flange head. In this case the top of the head is indented leaving a ridge running around the outside of the hexagonal head. There is often a secondary drive, a slot or Philips, in the head of this screw.

Socket Cap Screw Heads - The head style of the screw is unique to a socket and often installed flush with the surrounding materials.

Trim Head - It has a narrower head and is an option to flat head screws. These are used as a finishing screw for woodwork and carpentry.

Truss Head - These are also known as mushroom head due to its shape. The screws provide a larger bearing surface and have a lower profile than the pan.The rounded head top is much lower while the width of the head is wider, than pan or round screws of the same nominal size. This style head is used for a low profile, clean, and finished look. It is also desirable if there is not much clearance above the fastener.
