square allen wrench?

Unknown

I'm trying to remove the gas tank drain plug on my 54 Super Jet. The plug has a recessed 4-sided hole. Basically a "square allen wrench" would fit it. Unfortunately it is 5/16" so a 1/4 or 3/8 socket wrench by itself will not fit.



Does anyone know where I can get a wrench or socket to turn this?



Thanks!

try taking a spare 3/8 extension and grind it down slightly until it fits.

I removed mine by getting a 7/16 bolt and grinding the end square to fit the plug, and using a spanner on the head of the bolt. Crude but effective.

Unfortunately I don't have a grinder... really need to get one of those! Though I guess I could just use a file and be very patient. There must be a tool that fits this. Is it just hard to find these days?

instead of buying the tool that fits buy the grinder. lol

Hehe yeah I might wind up doing that. I've been meaning to buy a grinder anyway.

carlivar, go to your local hardware store or farm supply store and ask to see their assortment of square key stock. Square key stock is used commonly on electric motor shafts to hold the belt pulley in place. There are several different sizes, I think the Hudson's need a 1/4" or 5/16" if my memory serves me ! I use square key stock on my Hudson gas tank plugs, just turn the key stock with a crescent wrench. If the plug is stubborn, whatever ya do, don't heat the plug with a torch ! ! Tool peddler's such as MAC, MATCO, Snap-On, etc. have several 3/8" sq. drive sockets with various fastener drivers that have a square shank. You could use the socket along with your correct key stock & you'd have the tool you need for this application. Hope this help's you in some way, Good-Luck

I used an appropriately sized tap from a tap & die set to twist mine out. The fluting of the die is basically square; trial and error will point you at the right one.

I have a set of ezy-outs that have a square shanks of different sizes. I have removed the type of plug mentioned above using the the ezy-out "upside down" in the plug and a cresent wrench. Norm

I stuck a socket extension plus a screwdriver blade in the hole to make the extension wider on one side, and out came the plug. It wasn't on a gas tank, but on a rear axle a few years ago.

I tried heat mine up with a blow torch as it was stuck. The perimedics had a tough time getting me down out of the tree, but once I got to hospital they were able to patch me up. The fire marhall said the fire should burn itself out in a day or two. I would try grinding down the 3/8 extension, works better.
