that's because those parts are intended for commercial ground bonding 
purposes (electrical safety and lightning), not the bottom of a vertical 
antenna (RF ground). There's no need for strap in the former 
application, since RF losses aren't what they care about. They worry 
about good contact and mechanical security and installation time.

Connectors for thin strap are going to be a niche market, since there's 
just not that many vertical antenna installations to worry about.  For 
more "bar" like connections (e.g. 1/8x1" bar), conventional bolted 
connections work pretty well, and there are off the shelf lugs and bolts 
approved for the purpose.
