Ba - 10/5 Drain/fill Plugs. Finally An Easy, Off The Shelf Solution.

[skel130]

I recently changed to gear oil in my truck, and like many before me, struggled to find a tool to remove the 5/16 square hole plugs. At a tool store, when attempting to find a tool to use, I stumbled upon the best solution I've heard of yet. I present to you..............

 

 

 

 

The 5/16th keystock. Cut a 2-3 inch piece, and use a  5/16 box wrench. Presto, open without having to A) Ruin a good 3/8 extension, or B) Worry about rounding the hole with a mis-ground extension. 

 

Looky here: https://www.acehomecenters.net/products/key-stock-sq5-16x12-red%7C54254.html

 

Even ACE carries it. 

 

 

Wasn't sure where to put this little revelation, but hopefully someone finds this useful.

I replaced my drain plug with an M16 X 1.5 magnetic drain plug and the fill plug with an M18 X 1.5 oxygen sensor bung plug. No more special wrench needed.

I picked up the goofy tool of e-bay a few months back for a couple bucks shipped ... 8mm and 10mm square drive sockets in the package for use with my 3/8" ratchet. keep them in the glove box.

Look at my signature, it has never been more relevant than right now, haha. I found a threading tool with a square head that fit almost perfectly into the hole. I just used vice grips to clamp down the other end and turn. Worked like a charm, got it from Ace.
