Where do I find

[hardworkingstiff]

I need 3/8" and 1/2" allen wrenches that I can attach my 3/8" or 1/2" torque wrench to. They need to be about 5" long before the adapter for the wrench. The electrical supply houses don't know where to find them and Grainger didn't have any.

Help please.

Thanks,
Lou

Try your local tool supply house. or snap on tools. you might even get lucky at NAPA or other auto supply. good luck

I would try Northern Tools, Sears or try a search on EBay. I don't know whout the 5" long thing but I have a set that fits a 1/2" drive wrench that goes up to 3/4" I think. If you want to take out a bank loan then you could look at Snap On tools.

sometimes it pays to buy the more expencive tools, I only own 3 Snap On tools myself but I know they carry what he is looking for.

The hex key in most of the square drive allen wrenches is removable. I have taken a long standard allen wrench, cut the short arm off and used it to replace the key in the standard allen socket, for applications like this.

Ok, I'm going to tell on myself.

I use copper conductors to feed the 600-amp to 1,000-amp panels I install. I usually just stub up in the transformer from the panels. Since I've been involved with this forum I've decided I really do need to properly torque these conductors on the MB. The lugs on the MB are so deep and the access so narrow, that I need the 5" straight allen wrench to clear the face of the breaker. I know I'm not the only one installing this panel, so where have the technically correct installers purchased their allen wrenches to fit this application?

That's the only solution I've been able to come up with so far, I was hoping since this is needed by everyone properly installing the service conductors to these type panels that there would be a source. As far as cost, does it matter really? Buy it once for life, right?

Lou, any reason you can't just use a short hex bit and a 6" ratchet extension?

Yes, the breaker won't allow it. Square D really should do a better job of this, IMO.

Have a couple of those in my tool box as well. :)

A chop saw (abrasive wheel) makes quick work of an allen wrench.

Snap-On has what you need. But like I mentioned earlier check you local tool supply house we have one here called Ram Tool they are not on line though I found a number of places called Ram Tool on line. you should have a tool dealer somewhere close by check the yellow pages.

[iwire]

For what it's worth my 3/8" drive seven piece hex key set from Snap-On was over $100. The same set from craftsman with a rail was about $50.

Either one will twist up if you lay into it but the Craftsman is easily replaced compared to chasing a Snap-On truck.

I know I going to get slammed for this one but here goes nothing. When I run into a difficult allen wrench problem I go to the hardware store and buy a group 5 or group 8 hexhead bolt (groups 5&8 are very hardened bolts) that is long enough with a couple of nuts to lock it together at my socket. It works like a dream even though it's kind of funky.

I got mine at Sears, I need them for transformer testing to undo the neutral

I think you mean grade 5 or grade 8. that is an interesting way to takel the problem I just prefer a good tool with a warenty. The SnapOn truck makes house calls here Iwire.

Funny you asked this question. I just did it today! I have a set of rachet allens from Snap on. The allen part can be removed by losening a set screw on them. Then I cut the small end off my 3/8" allen wrench and installed the long end into the Snap-on socket/allen then attached that to my 3/8 torque wrench. It worked perfectly! I also ordered another 3/8" allen from the shop to replace the one I cut up.

Why not use the short (regular) allen sets that go to 3/8, and 1/2", then just use a long socket extention..... They make those in like 6-12".

I think Larry already said it.....

The holes in the breaker are are only large enough to fit the allen key not the 'holder' and the terminals are 3" or 4" deep in the breaker.

I would also try McMaster-Carr.

It's like Grainger on steroids.

[jimport]

Grainger has a set that goes up to 3/8". I have also purchased them singly.

There is one breaker that is (maybe was, as I haven't run into it in a few years) shipped with a special allen wrench where the short arm of the allen is shorter than normal. The heads of the set screw terminations face the side and not the front of the breaker. The only way to tighten them is with this short arm allen wrench. There is a torque spec, but I have no idea how you could use a torque wrench.

there are many styles of torque wrenches and there is one for this application. It has sockets that go in the end to fit different size allen's. I used one in the USAF. though I would be upset to have to buy a special wrench just to torque a few panel lugs.

McMaster-Carr sells 'hex key blades' which are not bent over.
www.mcmaster.com part number 6972A28

They also have 'extra short', 'short', and 'long' hex sockets, eg part 5494A83

McMaster-Carr is almost never the cheapest on anything, but they have just about _everything_, and in most areas deliver UPS ground the next day. The next time you need a left handed drill bit, they are the folk to call.

Try these guys. They have a selection of them. I don't know how these prices compare, but they've always been competitive on items I was looking for in the past.
