Hi there

I am rebuilding set of speakers and the stand attachment has a security/anti tamper allen bolt in it.  It is wikipedia under hex key it is a "Security hex socket(pin-in-hex-socket)" see below


Security hex socket(pin-in-hex-socket)  

My wife would prefer I buy this tool rather than trying to modify a allen key with a drill in one hand while holding the a set of pliers  with the allen key in other.

Where would you buy this kind of tool from? (I live north of the bridge in Auckland)

Is this something that will be at M10 mega/Bunnings in a pack of hex/torx bits?

Cheers
Jamie
