# Basic Features

## Side Face Hole Spacing

All holes on the .75” tall sides of the Tube Plugs are .5” from the end of the tube and have .5” spacing between holes. It is recommended to drill these holes using a CNC machine or other hole drilling fixture. If holes are drilled by hand, increase the drilled hole diameter to account for any inaccuracies.

{% hint style="info" %}
If drilling the holes by hand, refer back to the [Drilling Guides](/welcome/system-and-structure/tube-plugs/general-info/drilling-guides.md#drilling-guides) to find the jigs to ensure perfectly aligned and positioned holes for effortless installation of WCP Tube Plugs.

## Bolt C-Bore

All updated Tube Plugs now feature a Bolt C-Bore on each of the #10-32 threaded holes located on the bottom face of the block. This feature is designed to be used specifically with the #10-32 x 0.1875" L Alignment Pin (WCP-2115) and provides teams with an additional method of resisting slip and securely locking parts in place.

{% tab title="Alignment Pin Example" %}
The Alignment Pin is designed to have a low profile, as shown in the image below. With the 0.1875" long bolt head protruding only 1/8" from the block, providing a subtle but effective way to lock parts in place.
