I am looking for a nut to support the bolts that stop the hydraulic pressure of the crane this time
I found a round boss and purchased it.
Since the round boss penetrates, it is very easy to use because it also adjusts the bolt.
Because the visibility of the racetek side mirror attached to the super-seven is bad, I used this L dimension 25 mm D size 20 mm boss for extension on the left and right by two. Although considerably ingenuity is necessary for installation, the side mirror which became wide by 5 cm each side is greatly excellent visibility! It looks good with black frost painting as well. It was a very satisfactory finish.
I used it this time because it is not a normal pipe. Although it seems that usage like us is not supposed to be assumed, it seems to be useful in the future if there are 10 mm and 5 mm in length for fine adjustment.
