Understanding Bevel Head Screw Dimensions: An Essential Guide

Bevel head screws, also known as flat bevel hex socket head screws, are commonly made from stainless steel and are used in machinery to secure gears to shafts. They are available in a variety of sizes, including M4, M5, M6, M8, and M10. The head shape is typically chamfered, and the screw is driven or secured without a toolbox. Bevel head screws are used in home office equipment, marine assembly, and other mechanical industries. They are ideal for use on flat surfaces and in limited areas where the head needs to be flattened to secure the target.

Additional Information

When purchasing Flat Bevel Hex Socket Head screws, it is important to note that there may be slight variations in colour, size, and weight between the product image and the actual product received. These screws can be purchased from various retailers, including Amazon and The Home Depot.

Bevel Head Screw Materials

Bevel head screws are commonly used in machine parts, die fixturing, and clamping. The flat socket head enables driving where there is insufficient space for wrenches or sockets and allows the screw head to sit flush with the surface.

Bevel head screws can be made from a variety of materials, including:

Stainless Steel

Stainless steel is a common material for bevel head screws. It offers corrosion, rust, and stain resistance, making it suitable for environments with water exposure. However, stainless steel may not be fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments.

Carbon Steel

Carbon steel is another option for bevel head screws. It can be passivated and chrome-plated to enhance its properties.

Aluminum

Aluminum bevel head screws are also available and can be customized according to specific requirements.

Brass

Brass is a material that can be used for bevel head screws, offering a different aesthetic compared to other metals.

Copper

Copper is another material option for bevel head screws, providing good electrical conductivity and corrosion resistance.

Bevel Head Screw Uses

Bevel head screws, also known as countersunk screws, are used in a variety of applications where a flush finish is desired or required. Here are some common uses for bevel head screws:

• Finish Work and Decorative Applications: Bevel head screws are often used in finish work, such as woodworking or furniture making, where a smooth, flush surface is desired for aesthetic reasons. In these applications, the bevel head allows the screw to sit flush with the material surface, resulting in a seamless and visually appealing finish. To enhance the appearance further, flat head screw covers, also known as "beauty caps," can be used to hide the screw head.
• Drywall Installation: Bevel head screws, specifically those with a bugle head design, are commonly used in drywall installation. The bugle head automatically compresses the drywall paper and gypsum as the screw is installed, forming its own countersunk hole. This feature ensures a secure hold and a flush finish, making it ideal for drywall applications.
• Wood and Softer Materials: Bevel head screws are often the preferred choice for use in wood and softer materials. The countersunk head provides a flush fit and the necessary bearing surface to ensure a strong and secure connection. This makes bevel head screws ideal for woodworking projects, furniture assembly, and any application involving softer materials.
• Electrical Applications: Bevel head screws, particularly those with a fillister head design, are commonly used in electrical applications. The fillister head has a smaller diameter than a standard round head, allowing for assembly close to flanges and raised surfaces. This makes it suitable for electrical work where space may be limited. Additionally, the fillister head can be shaved and drilled, making it versatile for various electrical connections.
• High-Volume Assembly: In manufacturing and industrial settings, bevel head screws are often used in high-volume assembly processes, especially when pneumatic equipment is employed. The bevel head design allows for the transmission of higher tightening torque levels compared to other head styles, making it efficient and effective for mass production.

Bevel head screws offer a wide range of applications and are versatile enough to be used in various industries. Their ability to provide a flush finish, strong hold, and compatibility with different materials make them a popular choice for professionals and hobbyists alike.

Bevel Head Screw Installation

Bevel head screws are a type of countersunk screw, meaning they are designed to sit flush with the surface of the material they are being installed into. They have a flat outer face and a tapering inner face, allowing them to sink into the material. This type of screw is commonly used in machine parts, die fixturing, and clamping.

To install a bevel head screw, follow these steps:

• Ensure you are using the correct type and size of screwdriver for the screw head. Bevel head screws typically use a Torx drive, but they may also use a slotted or Phillips head screwdriver.
• If necessary, create a pilot hole in the material. This is especially important if you are using a harder material or if the screw is being installed close to the edge of the material.
• Place the bevel head screw into the pilot hole, ensuring that it is aligned correctly.
• Begin turning the screwdriver to drive the screw into the material. Apply firm and consistent pressure to ensure the screw is driven in straight.
• Continue turning the screwdriver until the head of the screw is flush with the surface of the material. Do not over-tighten the screw, as this may strip the threads or damage the material.
• If desired, you can apply a small amount of thread-locking fluid or adhesive to the threads of the screw before installation to prevent it from loosening over time.
• Once the screw is installed, check that it is secure by attempting to tighten it further with the screwdriver.

It is important to note that bevel head screws are designed for specific applications where a flush finish is required. They may not be suitable for all projects, and using the correct type and size of screw is crucial to ensure a secure and long-lasting installation.

Bevel Head Screw Alternatives

Bevel head screws, also known as countersunk head screws, are commonly used in machine parts, die fixturing, and clamping. They have a flat outer face and a tapering inner face, allowing them to sink into the material. The angle of the screw is measured as the full angle of the cone, and the flat socket head enables driving in tight spaces.

If you are looking for alternatives to bevel head screws, there are several options available:

Flat Head Screws

Flat head screws are designed to sit flush with the surface of the material they bind. They have a cone-shaped bearing surface under the head, with an angle of 82° in the Unified System (U.S.A.) and 90° in the Metric System. Flat head screws are commonly used in finish work and can be covered with a "beauty cap" to hide the head.

Hex Head Screws

Hex head screws have six sides and a flat top, making them the most common head type in fasteners. They can be tightened with almost any wrench of the correct size. Hex head screws are similar to hex flange heads, and often have a secondary drive, such as a slot or Phillips, in the head.

Round Head Screws

Round head screws have a flat bearing surface and general bearing strength. They are preferred for aesthetics due to their smooth appearance. Round head screws have a lower profile than pan or round screws of the same nominal size, making them ideal for a clean and finished look.

Dome Head Screws

Dome head screws also have a flat bearing surface and general bearing strength. They are often chosen for their smooth appearance and low profile. Some dome head screws have a flange around the outside, similar to a washer, to increase bearing force.

These alternatives to bevel head screws offer different features and benefits that may make them more suitable for specific applications. It is important to consider the functional and decorative aspects of each screw head style when making a selection.
