For preventing electrolytic corrosion of aluminum pipe connecting bolts
On 2017-11-10 18:22:40
The aluminum pipe connection hole is 10φ, the pipe connection stainless steel bolt is M8.
Because it is a pipe to be used outdoors, I used it together with the washer TT (teflon) part number 0822-10 of Hirougu instruments so that aluminum and stainless steel would not touch directly by touching it.
It is strong and scratch-resistant, and even if the bolt is tightened, plastic deformation in the length direction is few, and I met a very good product.
