Insulated electrical stand offs
Worked great for mounting bus bars in an electric panel, good robust parts

High Quality
The resin body is very tough. I appreciate having complete dimensions, since i'm using them in a tight space. I do worry about the long-time corrosion-resistance of the 'chromate-like' plating on the screws; wish they were stainless steel.

Bolt length
These work great I just wish the bolts were a little longer I believe the bolts are 8 mm x 1.25 thread, but of course this depends on your application as far as bolt length
