I use the GP hinges as well... but I toss a few in the bin out of every pack.
Randy, with these I don't see flash (oh, there is flash, I mean that just isn't the problem that makes them bind most of the time) as much as the pins are sometimes bent at a mid point, or sometimes a bulbous round enlarged area is in the middle of the hinge seam. It's smooth, but enlarged in that area.
Not sure of the why/how in the manufacturing process, but bottom line is if you buy the large pack of them, chucking a few isn't a big deal. Price of doing business as they say...

Like any injection molded part, they can get flashing in the gaps. A little work with a #11 usually cleans them up. I've had one or two with bent pins or similar problems that had to be tossed, but overall, no worries.
