Pin backs, also known as pin clasps or pin fasteners, are the mechanisms used to secure pins and brooches to clothing or other surfaces. Here are some common types of pin backs:
1. Butterfly Clutch
The butterfly clutch, also known as a butterfly clutch clutch back or a military clutch, is one of the most common types of pin backs. It consists of a metal backing with two small prongs that fold over the pin stem. The prongs can be squeezed to secure the pin in place and released to remove it.
2. Rubber Clutch
The rubber clutch, also called a rubber pin back or rubber stopper, is similar to the butterfly clutch but made of soft rubber. It provides a secure grip and is often used for pins that need extra stability or for people with metal allergies. The rubber clutch is easily slid onto the pin stem and can be removed by gently pulling it off.
3. Locking Clasp
The locking clasp, also known as a safety pin back or a screw-on clasp, features a threaded mechanism that securely locks the pin in place. It typically consists of a metal backing with a threaded post that screws onto the pin stem. The locking clasp provides a reliable hold and is less likely to accidentally come undone.
4. Magnetic Back
Magnetic pin backs use magnets to secure the pin in place. They typically consist of two separate pieces: a metal backing with a magnet and a metal disc that attaches to the pin. When the two pieces are brought together, the magnet creates a strong bond, holding the pin securely. Magnetic backs are easy to use and allow for quick and convenient attachment and removal of pins.
5. Stick Pin Clasp
Stick pin clasps are commonly used for stick pins and lapel pins. They feature a long, thin pin stem with a protective cap or end piece. The pin is inserted through the fabric and secured in place by removing the cap or releasing the end piece, which expands to prevent the pin from slipping out.
These are just a few examples of the different types of pin backs available. The choice of pin back depends on the type of pin, the desired level of security, and personal preferences.
