The Hole in a Safety Pin: Its Purpose

 

The hole near the clasp of a safety pin isn’t just decorative—it actually serves a functional purpose:

1. Locking Mechanism: The hole allows the sharp pin end to pass through or rest securely when closed, keeping the pin locked in place. This prevents accidental opening and pokes.

2. Ease of Manufacturing: Some designs use the hole to help shape and assemble the spring mechanism inside the pin.

3. Attachment Point (Optional): On some specialty safety pins, the hole can be used to attach threads, charms, or labels—though this is secondary to its main function.

So, that little hole is all about safety, stability, and sometimes versatility. Next time you grab a safety pin, you’ll know it’s doing more than just holding fabric together!
