Square Drain Plug Socket

[Scotsman]

Does anyone know where you can get a square drain plug socket to fit the plug on the oil pan, diff, and transmission of a TR3. Moss motors sell a wrench with a 7/16 head but I would prefer to have a socket. Its very easy to round off the head when using an open ended wrench as it tends to slip off.

Sears, MAC, MATCO, Snap-on, Cobalt.

I got mine out with a 3/8 drive extension and a screwdriver as a shim, then replaced them with a standard 1/2" pipe plug for about $1 each.

Other have bought a cheap 1/2 inch breaker bar and ground it to fit.

What you are looking for is a 7/16 "8 point" socket. Which as Larry wrote, should be readily available from Sears or any decent tool supply.

I have the sockets, but my preference is to replace the plugs with hardened magnetic hex socket plugs (that turn with an 'Allen' wrench). The plugs are just a few $$ at MMC.

I should have been more specific. The square ends of the drain plugs are male not female. ie the square end protrudes from the plug. The feedback and picture above show a female recessed square end. Sears, NAPPA, etc, etc do not have such a socket. As mentioned Moss have a wrench made for these plugs but I would prefer to have a socket that I can put on a breaker bar. I can replace plugs with contemporary plugs but would prefer to keep original.
The eight point sockets round off and strip the square plugs.

Right.

Well, that has certainly not been my experience. I suspect you are either thinking of a common 12 point socket, or are doing it wrong. If the plug is well and truly stuck, it might twist the plug in half, but it won't round it unless the flats were already badly damaged. I have used a breaker bar with my Sears 8 point socket many times. On occasion, when the plug was already damaged, I've had to use a pry bar to hold the socket down on the plug, but it still came out.

Thanks for your clarification. Yes I was using a 6 point socket. I was not familiar with the nuances between 6 and 8 point sockets. I was thinking that there would be a true square socket to fit the square head.
Point of interest. My local Sears store told me that the 8 pt sockets are no longer stocked instore and have to be ordered online. To avoid shipping costs (which are 2x cost of socket) you can go to store and order from there. They will ship to home. Sears was by far the cheapest place to order from.
