Need help identifying screw head...

[echang86]

Can anyone help me identify what type of screw head this is?

I thought it was a hexagonal, but none of my hex key on my 16 piece hex head set would fit.

Did you try your 16 piece metric set yet?

Maybe a T10 or T15 Torx ?

Hmm... I was thinking it could be a Torx. I'll give that a shot, and post up on my findings.

Did you try your 16 piece metric set yet?

I tried metric and s.a.e. Neither worked

That's an allen head screw. It appears to be a Torx because the hex shape was formed with a broach.

I borrowed a buddies allen/hex and torx set. Turns out it was a allen/hex the whole time. I was just missing that one size. Thanks for the help guys!

For those not aware, hex sockets are often formed with a broach that rolls "flower petal" shaped pieces of metal down into the bottom of the socket.
Those petals form what looks like a torx in the picture above, but the actual socket is a plain hex socket.
Other sockets are just formed by a punch and will have a smooth bottom to the socket.

Thanks! That clears it up alot!
