Hey Guys

Didn't want to make a new topic about this so i figured i would ask in here.
A few weeks back i received my smok TF-RDTA. After opening it up out of the box i noticed soemthing i never seen on a brand new tank. Seems like when it was being manufactured the QA guy went a bit overboard tightening my 510 pin. I looked at the screw on the bottom and it had a burr like most 510 pins get when you tighten with a flat head screwdriver. ( which is why i normally just use a old credit card or hard plastic to tighten/loosen them, cause they always seem to get damaged when screwing them in/out.
I thought no big deal, just a small burr. But the thing is it sticks out and is SHARP. I use a IPV5 and as you may know Pioneer for you uses those slotted 510 connectors, while other companies use the flat round connections. The first few times i screwed the TF-RDTA into the IPV5 i heard a grinding noise, and figured out it the damn burr from the pin on the atty causing the grinding noise! I look at the ipv5 510 connector and notice it's tearing the IPV5 510 pin apart! leaving a circle around it where it screws in, and noticed a bunch of gold looking debris all around it, like it's grinding it off everything i screw it down.
Sorry for the long post but wondering what i should do? should i unscrew the pin from the RTA and sand down the burr with fine grit sandpaper? I never received an atty like this before with the screw looking like it's been screwed on and off so much damaging the slot in the screw.
I have a new mod coming my way (smok H-priv) But am worried it will aslo start to damage that, but hopefully not since it's not a slotted 510 pin like the IPV. Any advice would be appreciated and sorry if it seems like i'm overreacting. Just want some reassurance that no damage will be done also using my other tanks on the now damaged 510 pin thats all roughed up from screwing the smok tank into it.
