snapfasteners

Snap fasteners, also known as snaps, press studs, or poppers, are a type of mechanical fastener commonly used in clothing and accessories. They consist of two parts that interlock when pressed together, creating a secure closure. Each part typically comprises a stud or socket and a corresponding post or eyelet. The stud usually features a rounded or domed head, while the socket has a recessed opening. When aligned and pressed, the stud snaps into the socket, holding the two pieces of fabric or material together.

The mechanism relies on the elasticity of the materials and the precise shaping of the stud and socket components. A slight deformation occurs upon engagement, allowing the parts to grip each other. To release the snap, a pulling force greater than the engagement force is required, causing the parts to separate. Snap fasteners are made from various materials, including metal alloys like brass or nickel-plated steel, and sometimes plastic. Metal snaps are often preferred for durability and a more substantial feel, while plastic versions can be lighter and less expensive.

These fasteners are widely used in a variety of applications. In clothing, they are found on baby clothes, shirts, jackets, trousers, and outerwear, offering a convenient alternative to buttons or zippers. They are also used in bags, luggage, tents, tarpaulins, and upholstery. The design of snap fasteners can vary, with different sizes, shapes, and strengths of engagement available depending on the intended use. The installation of snap fasteners typically requires specialized tools to press the components securely onto the fabric or material.
