ace vertical grip need torx size please

[nza]

Just picked up a rail that has an ace vg. It looks like it uses two very small torx or even hex screws to tension up against the rail. I don't have a torx or hex screw that long so I have to go out and buy one, but does anybody know what size of torx or hex it is? All my hex's are only about 2 inches long before they right angle. I don't want to ruin a set if I dont' have to. Ace isn't getting backto me either

My month old ACE vertical grip made of Aluminum has silver colored set screws that uses a 3/32 in allen wrench. The vertical grip also came with nylon screws for those who don't want to nick their rails. I used the metal set screws that screw in from the bottom----not the side. I found the sweet spot for its location and clamped it down tight. My grip is a short stubby model rather than the longer thin types made of plastic. Mine has two set screws. Again , 3/32 in . allen wrench. Hope this helps.
