Hole cutout is actually 1-7/8, not 1.77. It is very small and difficult to turn the sleeve. The connector posts are misaligned and will need to be adjusted if you wish to use a bare wire connector. If you prefer to use ring terminals instead of spade terminals on the back, the nut thread pitch is 4mm x 0.7.
