Ice screw issue

One of my Petzl screws has a bit of corrosion or something on the front inch or so. Thought it was just cosmetic but last weekend the same screw got welded in place about 1/2 way in and wouldn’t go further. We lead 15 pitches and it only happened twice and with the same screw.

Was in hylite with a buddy last week and I had a similar issue with one of his screws which looked similar.

Any recommendations on fixing this?  It almost looks like there is some plating that came off rather than just a simple corrosion issue so not sure if polishing it will solve my problem. 

That's definitely the failure of the plating. There's not much you can do to truly fix it. If it's new, you could ask Petzl about getting it replaced, but IME they tend to be exceptionally non-accommodating when it comes to screw defects.

was going to suggest that you could pay to have it re-plated @ a local shop but honestly it may be just as or more expensive than a new screw.

that sucks, sorry...

Shouldn't be a problem aside from your screw not looking nice and pretty anymore. A lot of my screws have that same issue but still go in the ice the same as when I bought them.

plenty of ice screws are on sale right now...

Sent Petzl pics and looks like there is a decent chance they will warranty it!

I have like 18 other Petzl screws and only had an issue with this one

I put my screws in front of the forced air vent when I get home but it’s possible this one didn’t fully dry.  Either way I’m stoked they might help me out.
