Wilesco boiler sight glass bolts...



...are less than relaxing to install. I found that by placing the flat rare earth magnet from a child's toy on one side of my 4mm wrench, I could place the nut in the wrench, then line it up under the bolt and sight glass flange...

...it all buttons up in less than 20 minutes. I tightened each bolt/nut a half turn in the order shown, until all were tight and snug. Wilesco does not provide guidelines, and I am no expert so you are on your own at this point. One should take care to tighten them evenly and carefully so as not to bring undue pressure on any one point of the sight glass, flange or gasket.
