Battery terminals that fit, and stay tight.
Designed, machined and tested in Taiwan — in our own CNC factory, not outsourced. A6061-T6 aluminium, independently tested by SGS and published in full. Sold on Amazon since 2023 under the Kaas name — now part of KUTNEX.
Find the right terminalRead the guidesDesigned & Made in Taiwan
Every terminal is cut, anodised and inspected in our own factory in Taiwan. Not assembled here. Not finished here. Made here, from bar stock to boxed part.
The aluminium arrives with a mill certificate, gets tested before it is machined, and the results are published on this site rather than described. That is what the label is supposed to mean.
Start with the question that matters
The most common reason a battery terminal gets sent back is not performance — it is that it did not fit. Too tall for the hood. Too wide for the tray. No room left to get a wrench in. So that is where our site starts, not with a catalogue.

Independently tested, not just claimed
Anyone can print "aircraft-grade aluminium" on a listing. We had ours tested by SGS, an independent laboratory, and we publish the report numbers so you can ask for them.
| Series | SGS report | Date | Result |
|---|---|---|---|
| STING | KK-25-09211A | 13 Sep 2025 | A6061-T6 composition verified · 46.0% IACS |
| Eagle | KK-26-04498 | 05 Jun 2026 | 48.0% IACS |
| FLEX | KK-26-04499 | 05 Jun 2026 | 46.7% IACS |
Electrical conductivity tested to ASTM E1004-23; IACS is the standard scale for how well a metal conducts. The aluminium is separately tensile tested to ASTM B557-15 — 52 ksi tensile, 50 ksi yield, against 6061-T6 specification minimums of 38 and 35. Machined and tested in Taiwan.

Guides
- Will a Multi-Way Battery Terminal Fit My Engine Bay?The clearance check to do before you order: hood gap, side-wall room, post-to-post spacing and whether you can actually get a wrench in.
- Battery Terminal Dimensions Explained: Height, Width and Post ClearanceWhat each measurement means, where to measure it on your own battery, and which one actually causes returns.
- How to Install a Multi-Way Battery Terminal, Step by StepNegative first, seat the terminal, torque in sequence, negative last. The full procedure with the mistakes that cause comebacks.
- How Tight Should Battery Terminals Be? Torque Values by Post TypeRecommended, minimum and maximum torque for the post clamp and the cable set screws — in N·m and in-lb.
- Why Battery Terminals Keep Coming Loose — and How to Stop ItFive real causes, a symptom table to find yours, and why tightening harder makes two of them worse.
Coming: Battery Terminal Fitment & Torque Guide
Post identification chart, the four measurements to take in your own engine bay, torque table, and a print-to-scale paper template you can hold against your battery before you order. Body dimensions are already published in the dimension table.
We are still measuring — every dimension in the guide is taken off the actual product rather than a drawing, and we would rather publish it late than publish a number we have not verified. There is no signup form here yet because we have nothing to send you yet. When the guide is ready this box becomes the place to get it.
