1.8t turbo to manifold bolt replacement

I've stripped one of my turbo to manifold bolts and need to replace. Does anyone know where I can get like for like replacements at a sensible price?

Or are there any cheaper alternatives that would do the job and withstand the heat?

The only one I found on ebay is £15! https://www.ebay.co.uk/itm/Audi-TT-8N-S3-1-8T-APX-BAM-Turbo-Manifold-Bolt-Brand-New-Genuine-06A145540K-/132314594334

cheers

Actually practically £16, don't fancy buying those, good question..
