As my own person experience, the real Pit Boss don't have screws but rivet in the arms and just one on the outside at the orbital. Moreover, the follow tips also can help you with spotting a fake Oakley pit boss. 1. The "POLARIZED" etching looked smaller and the print was blurry. In the real Pit Boss, the "D" of "POLARIZED" came up to the corner angle of the frame. In the replica, the "D" ends close to the T6 screw. The letters were too close together, looked narrower. 2. The lenses were not polarized, nor were they hydrophobic. I did the computer screen test and while the lenses did darken slightly at some angles, it never got truly dark as other polarized lenses would. As for the hydrophobic coat, the water beading was more similar to a pair of $5.00 plastic shades that I had lying around, rather than the really obvious hydrophobic beading I saw in my original X metal XX lens. 3. Suspicious rivets, I read that the replicas would have screws instead of rivets, but this one had actual rivets but the rivet surfaces were flat instead of rounded.
