you may not get all the parts other than that they seem good
Well they look strong i have not tested them yet tho i wish all of them came with the nut and washer. 3 of 4 is good tho now i need to get the washer and lock washer and nut ugg. Depending on where u are this is no big deal or is a pain.

Extremely well built with good materials and safety cover; stainless hardware.
Used these directly on several 100Ah batteries in a cabinet (non-marine). Not mentioned is the fact that the brownish material on bottom under screw terminal is actually some type of very hard plastic that is insulated. You will see all four of them in my picture. Mounting upside down worked here. Covers stay on. Highly recommend. Shipping is cost-effective (not oversized box).

Works as expected
Used this to wire in my bumper winch on both of my Jeeps. This is one of the easiest ways to add a fuse and change the amp rating without changing any wiring.

Works as expected.
Installed on the battery terminal to protect a solar charge controller. Easy to install and works fine.

Works great at a reasonable price
I use these directly on my marine batteries. They work great and allow for better protection being at the source of energy.
