Nut for Water Heater Element

Systems, Gear, & DIY
1

Anyone know where to source one of these? The element threads are 1" NPS, so I’d think it would be fairly easy to find, but no luck at my local hardware store. I’m going to go check the big-box store but I didn’t find anything on their website so I’m not optimistic.

Google turned up this: 1" SS NPS Locknut and o-ring kit
I don’t know that I can justify $12.50 for a single nut. Any online sources that won’t gouge me on price and shipping?

I don’t know if this site is helpful or not.

Around here there are dozens of appliance repair shacks.  It seems to me that they would be happy to sell you a used one from an old water heater for a buck or two.
