This is an aftermarket set made in grade 8 and yellow zinc, except for the thick washers. The nuts are the correct 12mm size and the washers are the correct thickness. They are all the correct M8×1.25 thread. The original came with 6 long, 6 mid and 2 short studs. Our kit comes with 12 long and 2 short studs as the difference between the mid and long is but a few mm. The set does not come with the lock washers as you can pick those up at any hardware store.
