wheel bolt length for locks/aftermarket wheels?

[auditude at cox.net]

Hello,

Does anyone know what wheel bolt length I should be using to bolt on a set of TSW's on a Coupe GT?  I want to buy some locks, but an unclear as to the correct length.

When I have access later on, I can measure the lug bolts I have, but I don't have access to them right now.

I believe the wheel bolts are 17mm hex, M14 x 1.50mm thread pattern, right?

Thanks,

Ken
