What is Button Head Cap Screws

Button head cap screws are a type of fastener recognized by their distinct low-profile head design, typically featuring a rounded, dome-shaped head with a cylindrical outer edge and a flat top. These screws belong to the family of socket head cap screws and are differentiated by their unique head shape.

Sizes

Button head cap screws come in various sizes to accommodate different applications. Common sizes include:

– M3
– M4
– M5
– M6
– M8
– M10
– M12

These sizes refer to the diameter of the screw, with varying lengths and thread pitches corresponding to each diameter.

Specifications

The specifications for button head cap screws are often outlined by industry standards like:

1. ISO 7380: This standard defines the dimensions, tolerances, and mechanical properties of button head cap screws. It specifies the head diameter, head height, thread length, and drive types for these screws.

2. ASTM F835: This specification covers alloy steel socket button head cap screws, indicating the chemical and mechanical requirements for these screws.

Advantages

Button head cap screws offer several advantages:

1. Low Profile Design: Their low-profile head allows them to sit flush or nearly flush with the material’s surface, providing a neat and smooth finish.

2. High Torque Capability: Despite their small head size, these screws can handle relatively high torque due to their socket drive design.

3. Aesthetics: Their appearance is often more visually appealing compared to other types of screws, making them suitable for applications where aesthetics matter.
