Yep, And I would rather have a low profile drain plug than a monster head sticking off of it. Hey, maybe a low profile plug with a strong magnet at an economical price!It's all subjective until its objective.
Yeah I know all about those kinds of allergies and it’s pretty bad:Those metal allergies are the worst kind.
Depends on a couple of things.. Stamped steel or cast aluminum pan? The other thing, which is the most important because you can't forget function, is the simple question of does it seal? I've honestly never had an issue with any drain plug in any application in all my years as long as its not overtightened or cross threaded although the stock steel pans with the drain locations in the bend of the pan left a lot to be desired.Yeah I know all about those kinds of allergies and it’s pretty bad:
“Metal hypersensitivity is a cell-mediated immune response that can lead to various diseases, including the granulomatous lung disease called Chronic Beryllium Disease. Hypersensitivity to metals also is increasingly recognized as one of the causes of joint replacement failure.”
Now from an engineering perspective, Only if I knew how different metals reacted with each other and how bolt size, thread pitch and torque settings are determined along with the thermal properties of differing metals - for best drain plug applications that is - I might could stand to make some money.
Speaking of drain plugs, do you recommend a rubber o-ring or are you a crush washer kind of guy?
