Very handy variety of the most useful sizes suitable for a host of bike parts. Great for the keen cyclist and bike repairer alike.
This set contains a comprehensive selection of M4 (only the grub screws,) M5 and M6 (4mm, 5mm & 6mm thread diameter) screws and washers.
A2-70 stainless steel, also known as 304 or 18/8 grade has great weather resistance and longevity. It can be used in all outdoor conditions apart from where consistent exposure to either salt water or sewerage is expected (they will outlast your bike and perhaps even you!)
