Dear members,
I am thinking of changing MOC of one of the exchanger channel cover bolts from B7 to B16 as the exchanger channel cover is leaking very frequently. Whenever it leaks we tighten it manually the leak minimizes after few days it resurfaces.In each tightening the nuts are moving by about 10 to 15 deg.
I request members to suggest whether the choice of B16 is OK are any other bolting material is better than B16 is available.
with regards
