Great Nuts & Bolts
I purchased a spare set of blades for my new Ego lawn mower. The blades are designed to be bolted together. The manufacturer of the blades does not include the nuts and bolts to tie the two blades together. I like to have a spare set of blades on hand for replacing when my original blades become dull.

Total Rip Off
I bought the blades and then discovered that the bolts were not included. OK. So I order the bolts, thinking they are pretty special to be costing $17.89, but no, they are just regular bolts you could buy and any hardware store for under $2. Shame on you guys for price gouging. You should have given the bolts away with the expensive blade you sold me.

OEM Bolts for EGO mower blades.
These worked as expected. Delivery was prompt.

Good but you need other bits to do a conversion.
The bolts themselves are great but to convert an LM 2100 to dual blade you also need the thinner fan and different hosel. I ended up getting a conversion kit with those so I didn’t need these bolts in the end.
