The present invention includes a device for providing a blind hole for making a removable connection to an enclosure. The device has a cylindrical shaft with a proximal portion and a distal portion. A head is formed at the distal portion of the shaft. The proximal portion of the shaft has external threads, which may by threaded into a hole of the enclosure. The proximal portion also has a tapped bore, axially formed in the shaft, which has internal threads to receive another threaded device. The tapped bore is closed at the distal portion, such that when it receives the other threaded device, the other device does not intrude into the enclosure.

1. A combination of an enclosure and device for providing a blind hole and removable connection to the enclosure, the combination comprising:a threaded opening extending through the enclosure; the device including a cylindrical shaft having a proximal portion and a distal portion; a head formed at the distal portion of the shaft; external threads formed on an external periphery of the proximal portion of the shaft, said external threads adapted to be removably threaded with said threaded opening; a bore having internal threads formed therein for removably receiving a threaded member in said proximal portion of the shaft, said bore having a closed end adjacent the distal portion; a through-hole extending transversely to said bore, said through-hole providing fluid communication between said bore and an external periphery of said head. 2. The combination of claim 1 wherein the device includes a flange formed on said shaft between said head and said external threads.3. The combination of claim 1 wherein the device includes; a flange transversely extending from the shaft and disposed between the proximal portion and the distal portion for seating the device from an exterior of the enclosure.4. The combination of claim 1 wherein the external threads include a fine pitch of approximately M6×0.75 and the internal threads of the bore include a fine pitch of approximately M4×0.7.5. The combination of claim 1 wherein the shaft includes a length dimension of the distal portion similar to a thickness dimension of a wall of the enclosure.6. The combination of claim 1 wherein the device is formed from passivated stainless steel.7. The combination of claim 1 wherein the head includes a slot for receiving a screwdriver for threading the external threads into a wall of the enclosure.8. The combination of claim 1wherein the device is threaded into the threaded opening of the enclosure with the head and the through-hole disposed externally of the enclosure, and the through-hole provides drainage of fluid from within the enclosure.
