I bought a mounting block for my outdoor light. It has a built in UL listed electrical box. The box is rectangular. I don't know what size the screws are as it is not a typical box. If it is 6-32, than I may not be able to use it? Will have to check the weight of the fixture and the screw size on the box.--checked box-has both 6-32 and 8-32 holes.

Calculating box volume is a matter of adding up individual volumes of assembled parts [314.16(A)]. Calculating conductor volume is a matter of adding up individual conductor equivalent volumes [314.16(B)(1) through (5)]. If box fill exceeds box volume, then you need to reduce the number of conductors or use a larger box.
