Metal snaps fasteners, also known as metal snap buttons or metal four-way fasteners, are widely used in clothing, bags, shoes, home goods, and other products. They consist of two opposing parts—a protruding part and a recessed part—and are designed to fasten quickly, securely, and durably. Due to their sturdy construction, durability, and aesthetic appeal, metal snap fasteners have become an essential accessory in many fashion products.

Types of Metal Snap Fasteners

Metal snap fasteners can be classified in various ways, including by design, structure, function, and material. Below are the common types and categories of metal snap fasteners:

1. By Structure:

• Flat-Type Snap Fasteners:

  • This type of snap fastener has a smooth surface and doesn’t create a noticeable protrusion, making it more streamlined and simple. It is often used in lightweight clothing and accessories such as shirts, T-shirts, etc.
  • The flat design ensures a more subtle and refined look, suitable for formal or minimalist styles.

• Round-Head Snap Fasteners:

  • These fasteners have a rounded protruding top, giving them a more three-dimensional and decorative appearance. Round-head snap fasteners are commonly used in outerwear, leather jackets, and jeans, offering both functional and decorative qualities.
  • The rounded design allows for a tighter fit, offering better durability.

• Oval-Type Snap Fasteners:

  • This type features an oval-shaped protrusion and adds a softer, more fluid look. It is often used in high-end fashion products or retro-style garments, providing a unique appearance.
  • Oval snap fasteners are less common but offer a distinctive visual appeal.

2. By Application:

• Clothing Snap Fasteners:

  • These are used in various parts of clothing, such as cuffs, collars, jackets, or pants. They are typically designed to be strong and durable to ensure a secure fastening.
  • Common materials: Brass, aluminum, and alloy.

  • Footwear snap fasteners are typically made from durable metal materials to handle frequent use.
