# Basic Features

## 1/2" Pitch Spacing

The WCP Ballast Blocks are designed around the [1/2" Pitch Spacing Standard](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing), making them fully compatible with [Punched Tubing](/welcome/frc-build-system/system-standards.md#tubing). This ensures teams can easily integrate ballast blocks into existing structures without the need for custom drilling or alignment adjustments.

## #10 Hardware

The WCP Ballast Blocks are designed to work seamlessly with standard #10 hardware, offering both tapped and clearance holes for maximum flexibility. This gives teams the option to use bolts directly for mounting or to pass through hardware for clamping and reinforcement.

## Bolt C-Bore

The WCP Ballast Blocks also feature integrated counterbores to allow for #10 hardware to sit flush with the block surface. This design prevents bolt heads from protruding into neighboring components, making it easier to package ballast blocks within tight robot designs.&#x20;

{% hint style="warning" %}
Due to the 0.125" depth of the Bolt C-Bore, it is recommended to use #10-32 BHCS bolts. If #10-32 SHCS Bolts are used, the socket head will protrude past the surface of the Ballast Block.
