What are those metal buttons called?

The metal buttons commonly found on clothing, bags, and accessories are generally referred to as snap buttons, rivets, press studs, or tack buttons, depending on their structure and function. These small yet essential fasteners serve both functional and decorative purposes, especially in garments like jeans, jackets, backpacks, and leather goods. Though often overlooked, they are vital in fashion, upholstery, and industrial design.

1. Snap Buttons (Press Studs)

One of the most common types of metal buttons is the snap button, also known as a press stud. It is a twopart or fourpart fastener that locks into place when pressed together. Snap buttons are made of brass, stainless steel, aluminum, or nickelplated metal, and they consist of two mating halves: the cap and socket on one side, and the stud and post on the other.

Applications: Used in shirts, baby clothes, bags, wallets, and sportswear.
Function: Offers a quick and easy way to open and close fabric without the need for sewing or threading.
Advantages: Durable, rustresistant, and available in various finishes, including matte, shiny, and antique styles.

Snap buttons can also be found in marine and outdoor applications due to their strong grip and resistance to corrosion.

2. Tack Buttons (Jean Buttons)

Tack buttons are metal buttons commonly used in denim jeans and jackets. Unlike snap buttons, they are not detachable and are designed for permanent fastening.

Structure: Consists of a button cap and a metal tack or rivet that is hammered or pressed into place.
Materials: Usually made from steel, copper, or zinc alloy with plating to prevent corrosion.
Usage: Ideal for waistbands and other highstress areas in denim clothing.

Tack buttons are prized for their strength and rugged appearance, often bearing embossed brand logos or designs, adding to the garment’s aesthetic value.

3. Rivets

Though not technically buttons, rivets are often mistaken for them. They are small metal fasteners used to reinforce stress points on garments and accessories, especially in jeans, belts, and bags.

Purpose: Provide strength to prevent tearing at joints and seams.
Types: Solid rivets, tubular rivets, and split rivets.
Materials: Brass, copper, or stainless steel.

Rivets are typically placed in spots where fabric layers overlap and experience frequent pulling or stretching, such as pocket corners and belt loops.

4. Decorative Metal Buttons

Some metal buttons are purely decorative, often used in fashion apparel, coats, uniforms, and traditional clothing.

Types: Shank buttons (with a loop on the back), flat buttons, dome buttons, and engraved metal buttons.
Designs: May include embossed logos, vintage patterns, enamel inlays, or gemstone accents.
Materials: Can range from alloy blends to plated gold, silver, or antique brass finishes.

These buttons are sewn onto garments and serve a stylistic purpose more than a functional one. In military and formal wear, they often carry symbolic or institutional meaning.

5. Magnetic Buttons

Magnetic snap buttons are commonly found in handbags, wallets, and purses. They consist of two magnetic discs encased in metal shells.

Function: Provide a convenient way to close flaps or compartments.
Advantages: Easy to use and longlasting, with a sleek, lowprofile appearance.
Limitations: Not strong enough for hightension applications like jackets or pants.

These are often hidden beneath the fabric but still contribute to the overall design of the product.

6. Choosing the Right Metal Button

When selecting a metal button for any application, several factors need to be considered:

Functionality: Does it need to open and close easily, or remain fixed?
Strength Requirements: Will it be under pressure, such as in denim or heavy bags?
Aesthetic Design: Should it match the garment’s style—vintage, modern, industrial?
Corrosion Resistance: Will it be exposed to water, sweat, or harsh environments?
Installation Method: Does it require a tool like a hammer, rivet press, or sewing machine?

The metal buttons found on garments and accessories go by many names—snap buttons, tack buttons, rivets, magnetic snaps, or decorative metal buttons—depending on their design and use. These components are more than just fasteners; they are essential elements that blend function, strength, and style. Whether you're wearing a denim jacket, opening a purse, or buttoning a shirt, these small but powerful metal parts play a critical role in both the usability and appearance of your favorite products.
