no screws are not included, depending what material you are fastening the brackets to will determine length of screws you buy

what number screw or type od screw head should be used?

#8 Phillips round head would be fine depending on what you're screwing it into. 1." - 1.5" L or up to a #10

Will this handlke 1/2" flex conduit (which is 1/2" inside but is perhaps 5/8" outside)?

If you wanted to bend each one out a bit they would. The gap measure between is .5" and that's a snug 0.5" The strap is plenty sturdy. ( Contract work that requires inspection. I do not know if it's legal to bend them ). The bracket is plenty strong. I used them to attach cattle fence panels to a wall. 3/4" bracket and bend it in may be easier.

BUENA CALIDAD

I was using the pre-filled 12ga flexible metallic conduit. That FMC can appear to be 1/2 in, but a 1/2 inch strap is too loose for that product. These 3/8in straps are the perfect fit and held the FMC firmly in place. Took a #8 screw without an issue, the mounting hole may even be able to take a slightly larger screw , not that it would be necessary. This is a good product and works very well. I am happy with this buy
