that fit, and stay tight.

CNC-machined from A6061-T6 on this floor — not sourced, not assembled. Every batch of aluminium is tested before it is cut, and we publish the results instead of describing them.

Anyone can copy the shape.
Nobody can copy the report number.

Copies are sold with the same profile and the same anodised colours. What they do not have is a mill certificate. Here is what the laboratory actually measured on ours.

61.9
HRB hardness
Nominal for this temper is 60. Three readings taken: 61.9 / 61.8 / 61.6.
50 ksi
Yield strength, 0.2% offset
ASTM B221 asks for a minimum of 35 ksi. Measured 43% above it.
52 ksi
Ultimate tensile strength
The minimum is 38 ksi. The metal is not the weak link in the joint.
Measured by SGS · tensile KK-26-05352 (ASTM B557-15) · composition ASTM E1251-17a · conductivity ASTM E1004-23 · RoHS EKR26601067.

Dimensional inspection before packing
Every batch is measured again after machining, before it is packed.

A terminal fails at the metal long before it fails at the design.

The profile is easy to copy. The anodised colours are easy to copy. What is harder is buying aluminium that is actually what the label says it is — and proving it before you cut a thousand parts from it.

Machining a terminal body
Bar stock in, terminal body out — one setup, one operator, one shop.
Finished terminals
Anodised in-house, so the colour is a finish and not a coat of paint.

The question that actually sends terminals back

It is almost never performance. It is that the terminal did not fit — too tall for the hood, too wide for the tray, or no room left to get a wrench in. So that is where this site starts, not with a catalogue.

Designed & Made in Taiwan

Every terminal is cut, anodised and inspected in our own factory. 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.
