What drill hole size is needed to use this bulkhead?

Use a 1-1/2 inch hole. The packaging confirms this. "Bulkhead Kit Assembly 1 1/2" hole"

I used a 1 1/2" hole saw. The bulkhead stayed leak free for over 6 months under the weight of 1 gallon of water. It could be tighter with a 1 15/32" bit, and it would be a very nice tight fit. The 1.5" hole saw left a tiny gap between bulkhead and edge, but never even noticed after I screwed the nut on tight.

I used 11/64 for screw. The panel of my draw is too thick, I had to use another 3/8 bit to drill half way to sink the screw head.

Requires a BIG hole. I was not prepared for the hugeness so We have to drill out a big hole. Haven't measured it yet, sorry

Standard threads should fit most all screw in broadheads. I recently used Muzzy's 100gr and some Cabelas expandables and they both fit perfectly.

Predrill hole 1/8 inch or 9/64 depends on screw that's in it. Then screw in

At the hardware store, get a closed circle hook with the appropriate weight limit. The package usually tells what size hole to drill for it. If it doesn't, you can hold a drill bit in front of the "screw" part of the hook. If you can see the entire threads of the screw on both sides of the drill bit at the same time, it's the right size.

use a 1/4'' drill bit, then a 1'' uni-bit to ream 3/4'' hole. it leaves less material to file for fine adjustment if needed

I use a combination of 3-1/2 and 4-inch deck screws. Pre-drilled with a 3/16-inch drill bit but only half the length of the screw that I was using. I used a piece of tape on the drill bit to indicate depth.

It requires an 11/32 inch or 9/32 inch drill, depending on the wall thickness of the trailer frame. The instructions can be downloaded from the Reese site.

I would like to say you'll need about a 7/8 to 1 inch hole. You do not need a rubber spacer for this. It is secured in place with 3 screws. I would recommend using a marine grade sealant around the base and in the screw holes.

Please see my review (end of May/beginning of June 2013)--I STRONGLY suggest an 11/32" drill bit for the best fit. Other sizes work; however, you may need to adapt the container or your installation process. As everyone else states, it is difficult to get these installed into certain containers & it's worth every penny!

the drill bit size is 31/64 and thats for a healy coil but if you do insterts you could do thick or thin and that would be a different size drill bit and depends on how much room you got to take up. i hope this helps norma

Use the hammer drill. Start with a bit one size smaller than what you need.

I never had to drill. my stock had removable plug I'm guessing 3/16. To match bit get one the size matching the core of screw not including the thickness of threads. Better to get smaller hole than the because threads will fit tight. If you were to drill larger than needed place a tooth pick with wood glue only on tooth pick. then screw the take a screw in place removing any excess glue.

No, the threads you see are for the nut that tightens the flange and holds the bulkhead in place. You need either a 1" nipple, onto which you can screw a female threaded fitting, or else a 1" male to femate threaded adapter. Either way, you need 1" male threaded fitting into the bulkhead.

I am not exactly sure what size hole you want in the 1" plate. I can drill through 3/8" plate with a 1/2" drill at 540 rpm easily using Mobil one as a lubricant. So with a sharp drill and using coolant (cutting fluids work best here) 1" should be no problem. You have to keep the chips clear and pull the drill out often to do that. You may have to stop and resharpen your drill or change it out for a sharp one. And do not force the drill through the steel, let it cut at it's own pace. Be patient and it can be done with no belt slippage and no motor stall. You do not need the lowest speeds to do that IF everything is clamped well. Do not try to hold onto the steel with your hand as you can be hurt easily.
