The reason why I got stuff of ebay is due to the fact that I work long days, away from any form of life activity (apart from the people I work with) and so getting stuff online is much easier. In addition I only needed 10-20 odd bolts and was almost sure that a normal store will ask me to buy bulk (or at least bags of 50). The photo above is posted simply out of curiosity as I'm not an expert on fasteners and so thought I'd ask before looking around for more.

@r0bsk1: this is actually where these came from

@D.C.: didn't think Screwfix does all the sizes I needed, although I'll check

@Jonathan: guess this proves what you are saying, I'll try to find something local and compare.
