    Answer This Question

    What is the insertion depth for the conduit?

    By|Jan 29, 2026


      Do these couplings have a 1/2" internal diameter and I assume they are used to couple 1/2 " metal conduit pipe together?

      Answer This Question

      The text of the webpage says it is 1". The answer to the question about inner diameter says it is for 1/2" emt pipe. The answer gives different internet & model #s than are listed on the specs part of the webpage. HOME Depot needs to fix this!

        0.706" or 18mm or approximately 45/64" would be the inside diameter. It fits the 1/2" EMT metal conduit. (Home Depot Internet # 100400405, Model # 853428, UPC Code # 091111020018, Store SKU # 203106, Store SO SKU # 1002243881)

          One of the five was missing a screw. Not in the package. The screw hole was improperly tapped so a screw would not fit without retapping the hole. Probably the packer left out the screw because it did not fit. Bad quality control.

          This Halex EMT connectors are much cheaper than the one Home Depot used to carry. It's also a product of less quality. I have more than 10% the screws cannot screw through the openings. It's ok to use, but far from good.

          Perfect for connecting pieces of EMT conduit. The only downside is that the Home Depot store in Norfolk, VA does not carry these in stock and have to be ordered online which causes a delay in getting the job done.

          I used these to connect galvanized tubing for a modular tomato trellis. Worked great.
