The washer spreads stress and strengthens the joint for a high torque application while the rubber washer cushions the joint against the hard surface.

They are all bonded together and have no sharp edges like you see on cheaply made washer products. I bought 2 bags of the #8 sized and not a one was separated, i.e. the washer separated from the rubber seal. The only small.issue is the holes.dont exactly fot the #8 self-tapping sheetmetal.screws I bought, but that could be the screws and not the washers. I mean, they will.work for my needs as the screw will just thread on to the washer instead of slipping through, which may be by design, so they are less likely to allow moisture to leak through. All in all, I'm very satisfied with the quality and price for what I got. :)

Bought to seal drilled drain holes on a flooded boat. Looks like they will make a good seal.

Hard to find item locally, Amazon had them to me the next day. Replaced the skylights, vents, and other plastic parts on the roof of my travel trailer. Wanted something to spread the load out to reduce the chance of breaking the plastic. Worked for what I needed to accomplish.

These were purchased to help waterproof mounting holes for polycarbonate roof panels. Made with stainless steel 304 grade. I'll let you know about durability. The sealing properties are good and I've found zero leaks so far with over a hundred installed so far. Working as they should be to this point.

Three Stars is MORE THAN FAIR Because the Edge of the Washers is Sharp!
