Answer This Question

Could these work on an incompressible material 3/32" thick?
ByJul 7, 2024
1 Answer | 
Answer This Question

You may end up with some imperfections in the flange when its installed, but you should be able to secure the grommet on something of that size.

    Will this work on a rubber floor mat for a car?
    ByFeb 11, 2024
    1 Answer | 
    Answer This Question

    No, it will not work on rubber properly and the thickness of the mat would most likely be too much for the unit as well.

      Why does nearly all of the equipment feel greasy/oily to the touch? I can?t use this without making a mess. Is this normal?
      ByMay 29, 2023
      1 Answer | 
      Answer This Question

      It is possible that the oils used during manufacturing remained on one of the parts and spread while the unit was packaged up. We do apologize for this. Washing the components with soap and water will remove that oil very quickly.

          Will this work on 10 ounce Army Duck canvas? I don’t intend to subject the holes to any rough treatment. I just want to make sure the hole maker can pierce the canvas and that the grommets will hold onto the fabric.
          ByMar 23, 2021

          Answer This Question

          Not sure of the thickness for 10 oz. Army Duck. I use these grommets to put additional holes in flags for mounting on motorcycles. The grommets go through two layers of canvas and the polyester flag material and hold well. The hole cutting tools dull quickly and are hard to sharpen. Instead of the hole tool, I: 1. mark the where the hole goes; 2. cut the fabric in an X; 3. push the bottom half of the grommet through; 4. pound them together. Works well on flags - pictures attached.

            Yes, it will, however, it might be easier to line it up better on a wider, flat, rock-solid surface. If you're using gromet pliers, pre-punch the hole completely. Goodluck!

              This kit worked for us including the fabric hole cutter. The grommet attaching tool worked perfectly.

              By|Apr 6, 2022

                I’m very handy but I’ve never installed grommets before. This was really easy and there were no do-overs necessary. All of the grommets set easily and without issue. What i a pleased with is that the tool offers an interchangeable 1/2” and a 3/8” grommet setter. The fasteners are really sound and seem strong. However I used mine on heavy GeoFabric. Am uncertain about Duck Canvas as i've never used it. For the price you really can't go wrong. Perhaps take a cloth sample to the Home Depot and test it first.

                  Should as long as the male side has enough length to swage onto the female side with the dye. The spread flange is what holds the grommet together. Never really seen any grommet lengths other than this size.

                  what is the thickness of the 3/8 when installed? I want to install on 1/16 panel and want to make sure its flush

                  Answer This Question

                  It adjusts to thickness as the die flares out the male through piece. But if you hammer too hard you could crack or cut your panel.

                  If the panel is a hard material like wood, the grommet will be about 1/16th thicker.

                  no mater what you use it for it will not be flush, remember you are putting two parts together and they are crimping together, the grommet fastening kit works very will, I have used it several times with great results. Just do not try to make it flat you will rune the grommet.

                    Yes you will have enough space to attach. I have never used these on anything but fabric.

                              Junk
                              I bought this to put 1/2 inch grommets in thin cotton canvas to make a lightweight tarp / cover. The hole punch has no edge, can't make a hole. I pounded on the cutter with a hammer and it just made a dent in the cloth. The 1/2 inch mandrel does not fit the anvil (3/8 does) but I tried anyway and it does not work. I have a lathe so I was able to machine the parts down to make things work, but I shouldn't have to. Also, the steel is not hardened as advertised.

                                Grommet wound up ripping a bigger hole
                                I followed the instructions, and while hammering the grommet together it tore through the canvas, leaving me with a huge hole that I now have to patch. It ruined my tent.

                                  First time adding grommets to anything and it was so easy. I cut up a fence screen to make curtains for or screened in porch. The fence screen had grommets every 2 feet, unfortunately once cut in 8 foot sections, the grommets did fall where we needed them. This kit made it easy with the hole punch and attachment tool. I did use a 2 x 4 instead of the small piece of wood provided. Everything worked great. I may be adding more grommets to a few camping tarps now that I know how easy it is.

                                  I’m on a quarantine driven garage organization spree, and this toolkit is just the ticket. Puches holes in everything I’ve thrown at it so far. I’ve done several pairs of work gloves so I can hang on pegboard, rubber boots and a flag. I will be needing more grommets soon!

                                    After using this kit to install grommets on my outdoor table cover, I wonder why I went so long without this product. Installing grommets with it is fairly easy and just takes some hard swings of a hammer. No more over-stretching bungees or tarps flying around! The kit comes with everything you need to install 1/2" or 3/8" grommets. It includes 6 of each size. Installing is easy, you bunch out the hole with a hammer then hammer the male and female ends of the grommet together with the tools supplied in the kit. These grommets can also be used on tents, curtains, straps, etc. The comes in a case which is great except the grommets tend to end up in other compartments of the case. The wood block (a backing for hammering holes in the tarp) that comes with the kit is a nice hardwood but will wear out over time. I tried using a 2x4 scrap which worked but was generally too soft for the job and did not work too well. Hammering the cutout hole in the tarp I find is the hardest part, you need to hammer around the edges of the cutter to makes sure you get a good hole. When adding grommets, if possible, fold over the edge of the tarp for added strength. Grommets are made of rust-resistant brass. This grommet kit is made in India.
