Klein Tools NRHDA3 – Frequently Asked Questions
1) Will the NRHDA3 fit my 1/2 inch drive impact wrench?
No. The NRHDA3 is not a 1/2 inch drive tool accessory, it is the part that creates the 1/2 inch drive. Its tool end is a 7/16 inch hex quick-change shank made for the Klein NRHD3. If your wrench already has a 1/2 inch square anvil, you need sockets, not this adapter.
2) How much length does the Klein NRHDA3 socket adapter add to the tool?
Overall length is 2.469 inches (6.3 cm), with a 0.45 inch body width and height. That extra two and a half inches of stack height matters in a tight panel or between studs, because it sits between the wrench anvil and the socket. Weight is 2.9 oz (82 g), so it adds nothing meaningful to the nose of the tool.
3) What part number do I order for the Klein NRHD3 socket adapter?
Cat. No. NRHDA3, which is also the manufacturer part number. It is a single-configuration item, one drive combination (7/16 inch hex to 1/2 inch square), so there is no size or finish to specify when ordering.
4) My older Klein socket adapter kept dropping sockets. Is the NRHDA3 different?
Klein calls out an improved pin detent on this socket adapter, which is the feature that retains the socket on the square drive. That is the change over the earlier version, and it is the reason to replace rather than keep fighting a loose one.
5) What is the Klein NRHDA3 made of, and will it rust in a service truck?
Alloy steel, AISI 4340 or AISI 9850, with a black finish applied for rust resistance. That is the standard combination for an impact-duty adapter that lives in a van and gets rained on.
6) Is the Klein NRHDA3 adapter made in the USA?
Yes, Klein lists the NRHDA3 as made in the USA. For agencies and utilities with domestic-sourcing requirements on tooling purchases, that is the answer on this part.
