## Description

This car battery adapter socket is made of high-quality pure lead, rust-resistant and corrosion-resistant, which is a soft metal with toughness and malleability, and provides excellent conductivity.Specification：Brand: SMILFUYName: Car Battery Post ShimsColor: SilverMaterial: Pure LeadSize: Approx. 0.7×0.6 inchApplicable: Most vehiclesFeatures:-This car battery terminal adapter sleeve has good weather resistance, which can withstand all kinds of weather.-This car battery terminal adapter sleeve is light in weight, which is convenient for you to carry and use.-This car battery terminal adapter sleeve doesn't take up much storage space, allowing you to easily store it when not in use.

Review: These are perfect for standard top-post car batteries. But the clamp I needed it for is a strange, thin-walled clamp that wouldn't open far enough for the shim. Yet fully tightened it was moveable by hand. Standard clamps would be no issue. These are nicely made and will be a great solution for regular-sized clamps. I am keeping these - confident in their value and should myself or a friend need one.

Ridiculous and completely useless. These “shims” are too small. Smaller than the battery terminal and too thick. As is being too thick, they won’t work under a battery clamp as it will take up too much space on maybe half a side of the terminal and make for poor contact and unable to secure the factory clamp without deforming it. Useless junk.
