tool(s) for rekeying Master ProSeries 6121 padlock

Torx?

allen wrench- get a new set and you will not ruin the socket head cap screw, using old worn out one will ruin the screw.

I dont know what size it is maybe 7/64"

I'm not sure either; I just know that a filed-down hex wrench from my grandfather's kit fit it perfectly.

Master probably has a spec sheet on these which would give you the proper size plus info on what size pins and springs it takes and so on. Contact them directly?

I've sent them an email asking the question. Their website is so marketing-oriented, it took a small bit of digging to find the right page to ask the question.

_The Complete Book of Locks and Locksmithing_ (5th ed., p. 205) provides half the answer, "an appropriately sized hex wrench".

Thanks, all, for the helpful replies.

But but but... that makes _sense_! Is that allowed here?

Don't forget to check metric as well as fractional inch.

Or: Just go out and buy a decent set of hex wrenches, both inch and metric, and be done with it. If you're going to continue mucking about with anything mechanical, you're gonna need 'em all sooner or later; better to make the (rather small) investment and have 'em on hand rather than going through this all again next time you're handed something odd.

The mounting screw ( part number Master 6121-0422 ) is a stainless steel socket head cap screw 7/64 x 15/16.

So the correct tool is a 7/64" hexagonal wrench (allen wrench).

I actually tried this before posting, and we weren't able to find a fit.

I've since heard back from Masterlock, and it turns out to be a 7/64" hexagonal wrench.
