About KUTNEX

A CNC machining company that decided to put its name on the parts.

KUTNEX is operated by Maoyu Technology Co., Ltd., a precision CNC milling factory in Taiwan. We do not outsource production — the terminals are cut, anodised and inspected in our own building.

Our products have sold on Amazon since 2023 under the name Kaas, which continues as the name of our full-size terminal series. KUTNEX is the parent brand that new series launch under.

Why machined and not cast

Most battery clamps are cast or stamped, which means the surface that grips your battery post is approximately the right shape. We machine that surface, so it matches the post taper. That single decision is behind most of what our terminals do differently — see why terminals come loose.
