A pin brick, based on specific types of building blocks, is a version of a 1x2 brick that contains a thin, round "pin" in the center of the inside of the brick. This internal structure differentiates it from other 1x2 bricks which are simply hollow inside.
Understanding the Pin Brick
Building blocks, like the common 1x2 brick, often come in slight variations that affect their internal structure and how they connect or fit together. According to Block Builders Guide, 1x2 bricks specifically can be found in two primary styles.
- Style 1: Without a Pin: These 1x2 bricks are entirely hollow on the inside. They offer maximum internal space.
- Style 2: With a Pin (Pin Brick): These 1x2 bricks feature a solid, thin, round pin located centrally within the hollow space.
Key Characteristics
The defining feature of a pin brick is this internal pin. While seemingly a small detail, it can potentially influence factors like:
- Internal friction when connecting to plates or other bricks.
- Compatibility with certain internal elements or rods.
- Overall weight distribution (though minimal).
Let's compare the two types mentioned:
| Feature | Without a Pin | With a Pin (Pin Brick) |
|---|---|---|
| Internal Space | Fully hollow | Partially occupied |
| Central Feature | None | Thin, round pin |
| Identification | Hollow interior | Internal pin visible |
Practical Considerations
Knowing the difference between a pin brick and a hollow brick is useful for builders:
- When following specific building instructions that might require one type over the other for structural integrity or internal connections.
- When sorting or collecting blocks, as this is a recognized variation.
- Understanding subtle differences in how pieces connect.
For example, inserting a rod or axle into the bottom of a 1x2 brick would be impossible with a pin brick, but feasible with a hollow one.
In summary, a pin brick is simply a variation of a standard 1x2 building block, distinguished by a specific internal structural element – the pin.
