Flange Button Head Allen Screw

Description

Flange button head Allen screw stands out for its unique blend of style, strength, and ease of use. Common in automotive, industrial, and consumer applications, this fastener is known for its streamlined appearance and reliable performance.

Low profile head facilitates space saving and safety.

These are protective fasteners which provide the assembly with structural support as well as a visually appealing look. It protects the components around it from damages like scraps and unintentional cuts.

Another advantage of these screws is the large under head bearing surface – this eliminates the need for washers. The Flange distributes the pressure better.

Basic Design and Structure of flange button head Allen screw

The flange button head Allen screw is composed of three defining elements:

a. Button Head

The button head is a rounded, dome-like head that sits above the surface of the material. It is lower in profile than socket head cap screws and more aesthetically appealing than hex bolts. The larger diameter provides a broader contact area, which helps prevent damage to the surface of the material being fastened.

b. Flange

The integrated flange is a built-in washer-like extension under the head. It distributes the clamping load over a larger surface area compared to standard screws, which:

• Reduces the risk of surface deformation.

• Increases stability in the assembly.

• Eliminates the need for a separate washer.

This built-in feature simplifies installation and enhances the structural integrity of the connection.

c. Allen Drive (Hex Socket)

The Allen drive, also known as a hex socket or internal hex, is a cylindrical recess in the head of the screw that accepts a hex key (Allen wrench). It offers several practical benefits:

• Allows for a clean and flush installation.

• Provides good torque transmission.

• Reduces the risk of stripping compared to slotted or Phillips drives.

Common Applications of flange button head Allen screw

The design of the flange button head Allen screw makes it useful in a wide array of industries and products, including:

• Automotive: Used in body panels, interior fittings, and under-hood applications where a secure and flush fit is essential.

• Electronics and Enclosures: Suitable for mounting circuit boards, securing covers, and assembling casings due to its compact head.

• Furniture and Fixtures: Frequently used in flat-pack and modular furniture for its sleek appearance and ease of assembly.

• Bicycles and Sporting Goods: Found in handlebar clamps, brake components, and other areas requiring lightweight, low-profile fasteners.

• Industrial Equipment: Used in machinery guards, panel mounting, and general assembly where robustness and removability are important.

• Construction and DIY Projects: Ideal for use in metal, plastic, or wood structures that require repeatable fastening.
