98% of People Don’t Know What the Hole in a Safety Pin Is For
At first glance, the tiny hole at the end of a safety pin might seem unnecessary. But it actually serves several important purposes that make the pin functional, durable, and versatile.
1. Provides Structural Strength
The hole allows the metal wire to bend and twist in a way that creates spring tension. This tension keeps the pin tightly closed and prevents it from opening accidentally. Without the hole, the pin would lose flexibility, making it weaker and more likely to bend out of shape.
2. Ensures a Secure Locking Mechanism
The hole acts as an anchor point for the spring action. When you press the pin, it snaps back into place, locking firmly. This ensures that the pin stays securely closed, whether used on fabric, clothing, or other materials.
