These are custom finished bolts that I have made for the kits. 12mm long in total. M5 Countersunk Head. Use a 3mm Hex Key. Price is for 6 bolts. Carbon Steel bolts that have been Black Zinc Plated. These leave very little residue on your hands and have a good quality black finish. As I have a surplus of these I'm happy to sell them. The price is for 6 bolts - if you want more just order more units of 6. These will be hand picked once ordered and placed in a small zip-lock bag. If you order more than one type of bolt they may be in the same zip-lock bag. Ideally these should be ordered with other products as I am not a bolt supplier but think these will be useful for the adapters and spacers I sell where bolts are not included.
