Abstract
A depth gauge used to measure a countersink of a hole drilled into a surface that is not orthogonal to the hole. The depth gauge includes a displacement indicator and an alignment device. The displacement indicator includes a main body and a displaceable member. The alignment device includes an extension member coupled to the displaceable member of the displacement indicator. The extension member is sized to extend along a radial axis of the displaceable member and has a diameter that is approximately the diameter of the hole to ensure alignment between a centerline of the hole and a centerline of the displaceable member. The alignment device also includes a swivel assembly having a fixed portion coupled to the main body of the displacement indicator and a base in rotational engagement with the fixed portion to ensure that the displaceable member is properly displaced with respect to the surface.
