When drilling a hole in a wood pole, how much larger should the hole be than the bolt size?

The correct answer is that the hole should be 1/16 inch larger than the bolt size when drilling in a wood pole. This specific size allows for proper clearance and ensures that the bolt can be easily inserted without binding or causing stress to the surrounding wood. A hole that is just slightly larger than the bolt provides enough space for expansion due to changes in temperature or moisture, which can cause the wood to swell. Additionally, a 1/16-inch difference minimizes the risk of the bolt wobbling or allowing excessive movement, which can compromise the integrity of the installation.

Using too large of a diameter for the hole may lead to a loose fit, which could affect the stability and strength of the connection, whereas a hole that is too small could hinder the installation process and potentially damage the bolt or the wood when force is applied. Therefore, 1/16 inch is considered the ideal compromise for maintaining secure and robust connections while allowing for proper fit and adjustment.
