Button Head Cap Screws: For applications where space is limited or aesthetics matter, our button head cap screws are the perfect solution. Their low-profile design offers a sleek appearance while still delivering robust fastening power.  

A button-head cap screw is a type of fastener with a rounded, dome-shaped head and a cylindrical shaft. This head style is characterized by its low-profile design, which provides a sleek and compact appearance when installed. Button head cap screws are commonly used in applications where space is limited or where a more aesthetic finish is desired.

The head of a button head cap screw typically features a recessed socket drive, such as hex-socket or six-lobe drive, which allows for secure tightening using a corresponding tool. This design not only provides a clean and flush finish but also offers excellent torque transmission and resistance to stripping.

Button head cap screws are widely used in industries such as automotive, electronics, machinery, and furniture assembly, among others. They are suitable for securing components in place where a flat or countersunk head screw may not be feasible or desired.

Overall, button-head cap screws offer a combination of strength, versatility, and aesthetics, making them a popular choice for a variety of fastening applications.

Button head cap screws are manufactured to various specifications and standards to ensure their quality, compatibility, and performance in different applications. Some of the key specifications and standards include:

  1. ASME B18.3: This standard, published by the American Society of Mechanical Engineers (ASME), provides dimensional and performance requirements for socket head cap screws, which also cover button head cap screws. It includes details such as thread size, thread pitch, head dimensions, and material properties.
  2. ISO 7380: This is the International Organization for Standardization (ISO) standard for button head socket cap screws. It specifies dimensions, tolerances, and technical requirements for these fasteners, ensuring interchangeability and compatibility across different manufacturers.
  3. ASTM F835: ASTM International publishes this standard, which covers the requirements for alloy steel socket button head cap screws. It specifies the chemical composition, mechanical properties, and other relevant characteristics of alloy steel screws suitable for various applications.
  4. DIN 7380: This is the German Institute for Standardization (DIN) standard for button head socket cap screws. It provides detailed specifications for dimensions, tolerances, and material requirements, widely used in European markets.
  5. Customer-specific Requirements: In addition to industry standards, button head cap screws may also be manufactured to meet specific requirements specified by customers, particularly in specialized applications or industries with unique demands.

By adhering to these specifications and standards, manufacturers ensure that button head cap screws meet the necessary quality and performance criteria, providing reliable fastening solutions across a wide range of applications.
