The Ultimate Guide To Bevel-Conical Head Screws

Bevel-conical head screws, also known as countersunk head screws, are used in machine parts, die fixturing, and clamping. They are identified by their 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. Bevel head screws are commonly used in applications where there is insufficient space for wrenches or sockets, and they enable the screw head to sit flush with the surface. These screws are often made from stainless steel, which offers corrosion resistance.

Bevel head screws are used in machine parts, die fixturing, and clamping

Bevel head screws, also known as countersunk head screws, are used in a variety of applications, including machine parts, die fixturing, and clamping. They are characterised by a flat outer face and a tapering inner face, allowing them to sink into the material and sit flush with the surface. This type of screw is particularly useful when there is insufficient space for wrenches or sockets, as the flat socket head enables driving in tight spaces.

In machine parts, bevel head screws are used to fasten and secure components together. They are commonly used in applications where there is limited clearance above the fastener, as their low-profile head design provides a clean and finished look. Additionally, the flat head of the screw allows it to sit flush with the surface, ensuring a smooth and uninterrupted finish.

Die fixturing is another important application of bevel head screws. In this context, they are used to securely hold and position dies during manufacturing processes. The flush fit of the screw head ensures that the die is held firmly in place without any protrusions that could interfere with the process.

Bevel head screws also play a crucial role in clamping applications. Clamps are used to hold workpieces securely in place during machining or assembly operations. Bevel head screws are ideal for this purpose as they provide a strong and secure clamping force while sitting flush with the surface. This helps to ensure that the workpiece is held firmly without any protruding screw heads that could obstruct the work area.

The angle of the bevel on the screw is an important consideration. In the Unified System (U.S.A.), the standard angle is 82 degrees, while in the Metric System (used in most other countries), the angle is 90 degrees. This angle affects the depth of the screw head and its ability to sit flush with the material. Customisable bevel head screws are also available from certain manufacturers to meet specific requirements.

They are also known as countersunk head screws

Bevel-head screws are also known as countersunk head screws. They are characterised by a flat outer face and a tapering inner face, allowing the screw to sink into the material. The angle of the screw is measured as the full angle of the cone. The flat socket head enables driving in tight spaces where there is insufficient room for wrenches or sockets. The screw head can sit flush with the surface.

Countersunk screws are used in machine parts, die fixturing, and clamping. They are also used in finish work, where a flat head screw cover can be used to hide the head. This is often done for aesthetic reasons, with plastic caps available in colours that match common plastic laminates and wood.

The countersink is the conical hole cut into a manufactured object, or the cutter used to make such a hole. The countersink allows the head of the countersunk bolt or screw to sit flush with or below the surface of the surrounding material. A counterbore, by comparison, makes a flat-bottomed hole that might be used with a socket-head cap screw.

The basic geometry of a countersink (cutter) can be applied to plunging and milling applications. Countersinks also overlap with chamfering endmills (endmills with angled tips).

Bevel head screws are used in gun manufacturing

Bevel head screws, also known as countersunk head screws, are used in gun manufacturing. They are characterised by a flat outer face and a tapering inner face, allowing the screw to sink into the gun's material. This is particularly useful when there is insufficient space for wrenches or sockets, and the flush finish is desirable.

Bevel head screws are commonly used in machine parts, die fixturing, and clamping. In the context of gun manufacturing, they are used in grips. For example, the Cajun Gun Works company uses bevel head screws for their Shadow 2, Tactical Sport models, and CZ-97 with aluminium grips. These screws are made from 4140 steel, heat-treated, and are designed to be used with a Torx 20 bit.

It is important to note that bevel head screws are not factory parts but meet or exceed OEM quality. To prevent the screws from loosening, it is recommended to clean the threads in the frame and the grip screws with acetone and then apply a small amount of blue Loctite to the screw threads.

The angle of the bevel head screw is measured as the full angle of the cone, and this angle determines how far the screw sinks into the material. This feature is advantageous in gun manufacturing, where a flush finish is often desired for both functional and aesthetic reasons.

They are made from 4140 steel and are heat treated

Bevel-conical head screws are made from 4140 steel and are heat treated. 4140 steel is a widely used medium carbon steel that is often referred to as chromoly steel due to the inclusion of chromium and molybdenum alloying elements. Heat treatment further enhances the material properties of 4140 steel, improving its strength, toughness, and hardness.

The process of heat treatment involves heating and cooling the steel to alter its microstructure and improve its mechanical properties. In the case of 4140 steel, heat treatment can lead to the formation of martensite, a hard and strong form of steel microstructure. This treatment results in screws that can withstand high stress and strain without deformation or failure.

The bevel-conical head screws made from heat-treated 4140 steel offer superior performance in applications requiring high strength and durability. These screws are commonly used in machine parts, die fixturing, and clamping. The heat treatment process ensures that the screws can handle the stresses and loads encountered in these applications without failing.

Additionally, the heat treatment of 4140 steel provides benefits beyond enhanced mechanical properties. It can also improve the corrosion resistance of the screws. This is particularly advantageous in environments where the screws are exposed to moisture or chemicals that could cause corrosion. By selecting bevel-conical head screws made from heat-treated 4140 steel, users can benefit from increased resistance to corrosion, ensuring the longevity and reliability of their applications.

Bevel head screws are used in furniture

Bevel head screws, also known as countersunk head screws, are used in furniture to provide a flush finish. The screw has a flat outer face and a tapering inner face, allowing it to sink into the material without any protrusions. This is particularly useful when working with furniture, as it creates a smooth and seamless appearance.

The angle of the bevel head screw is measured as the full angle of the cone, and it sits flush with the surface of the material it is binding. This type of screw is commonly used in furniture assembly, as well as machine parts, die fixturing, and clamping. The flat socket head enables driving in tight spaces where there is insufficient room for wrenches or sockets.

Bevel head screws are often made of stainless steel, which offers corrosion resistance and strength. They can also be customised to meet specific requirements, such as in the case of custom-made furniture. The screws come in various sizes and can be ordered in bulk, making them suitable for both small and large furniture projects.

When using bevel head screws in furniture, it is important to consider the drive style or drive recess. This refers to the type of tool needed to install or remove the screw. Common drive styles include slotted, Phillips, hex, square, and Torx®. Selecting the correct drive style ensures that the screw can be properly tightened and reduces the risk of damaging the screw head or the furniture surface.

Overall, bevel head screws are an essential component in furniture assembly, providing a secure and aesthetically pleasing fastening solution.
