How it connects
A separate clamp surrounds the rod and is tightened to retain the grounding conductor in electrical contact with the electrode. It forms a mechanical and electrical bond; no fluid seal is involved.
Male and female halves
The exposed rod surface fits inside a ground rod clamp. Male/female terminology is descriptive for this connection.
Usually connects to
- Ground rod clamp rated for the rod diameter and electrode material
Common sizes
- Nominal 5/8 in rod, reported actual diameter about 0.63 in (16 mm). Use the specified 5/8 in clamp fit; broader tolerances are not established.
Where it is used
Electrical grounding and bondingGrounding-electrode conductor termination
How to recognise it
Look for a plain round solid electrode shaft with no mating thread at the clamp location. Verify rod diameter and material against the clamp specification. For a galvanized steel rod, a photograph alone cannot establish material compatibility.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| Threaded ground rod coupling | A threaded coupling joins rod sections using mating threads; this interface grips the smooth shaft externally. |
| Pipe socket or slip fitting | The target is a solid grounding electrode gripped by an electrical clamp, rather than a hollow pipe inserted into a fluid fitting. |

Good to know
This is a descriptive clamp-mating surface rather than a named connector standard. Check clamp compatibility with the rod material; an estimated 25 mm contact length does not define fit.
