Old Parker - Kalon Nails
I wish Chris-Nick could acquire whatever is left of PK. This would avoid the confusion of mh nails being called pk's. Also, mh stands for ManHole. This is another point of confusion. "Fd. MagHub Nail" is not as easy to type as Fd. PK in C/L.
I'm sort of a stickler. If my plat says "Fd. 3/4" pipe", it should not be actually a 1" pipe. We are surveyors. We measure, document, and provide a historic trail. This trail should not be filled with discrepancies, unless we want our veracity to be questioned.
We sometimes will be dead, gone, or in the nursing home, when this young fancy surveyor retraces our work. If we are reliable surveyors, our work will live on in honor. If we are leaving a trail filled with discrepancies, then we will live on in infamy and dishonor.
Leave a good trail.
I don't set many things in places where I need a PK nail anymore.
They were absolutely necessary when setting in any road during winter and in concrete anytime.
An engineering firm I worked for would only get the 3/4in PK nails and they were a finger buster whether it went in or not.
Now I drill a hole and put in all or part of a 60d and stamped washer or other adequate from rebar with a cap to round head bolt over a stamped washer.
"Fd. MagHub Nail" ? What?
I'm finding M/H nails, generically called PK nails.
MagHub nails are the replacement for the (now defunct) PK nail.
If we are being precise, the ChrisNik replacement for PK nails is the MagNail. MagHubs are more like a 60 penny nail and come in 4", 6" or 8" lengths. The MagSpike is a longer thicker version of the MagNail.
I'm not sure I can (or would) use either for anything other than control in the states I'm licensed in.
