As well as a wide range of tools and welding equipment they supply a wide range of nuts, bolts and fasteners in all sizes and thread pitches.
I picked and selection of small (M2 and M3) hex head (Allen key) bolts and nylock nuts
They are also very helpful at matching up a random bolt you take in to a new one of the same size and thead pitch
