THE LARGEST OPENING THE PRODUCT IS PUBLISHED AS FILLING - a bondline gap between mated parts, or, for a leak-sealing product, the largest aperture it will plug. THE SLOT HOLDS BOTH SENSES AND THE DEFINITION SAYS SO OUT LOUD, on the adversary's [A-7] amendment: a gap between two mated parts and a hole in one part are not the same opening, and putting both in one slot without naming both would be an [L10] homonym. The bond-gap sense: LOCTITE 638 for bond gaps that `can approach 0.25 mm`, 577 `gap performance to 0.25 mm (0.01 in)`, 3090 `undefined bond gaps up to 5 mm (0.2 in)`, 5188's `Sealed to Maximum Induced Gap, mm`. The aperture sense, and it is what makes the radiator stop-leak's fold honest rather than lossy: Holts publishes Gun Gum as fixing `small holes in your exhaust, up to 20 mm` and K-Seal publishes repair of holes up to 0.635 mm under ASTM D3147. Without the second sense named, the stop-leak's number has nowhere to go. THE TWO SENSES ARE ONE QUESTION - how big a void will this close - and the makers answer it in one field with one unit. It is the fact Henkel's own retaining-compound selector is BUILT ON: the chart chooses between LOCTITE 603, 641, 648, 620, 638 and 660 by gap band alone - 0.15 to 0.25 mm for one group, 0.25 to 0.5 mm for the next - and the trade names parts by it, Maedler cataloguing 638 as `Retaining Compound, High Strength, for Large Gaps`. Per product: 638 is published for bond gaps that `can approach 0.25 mm`, 577 offers `gap performance to 0.25 mm (0.01 in)`, SI 5910 is `suitable for gaps up to 1 mm`. It separates real products that agree on chemistry, cure, duty and strength - 603 and 638 are both anaerobic acrylic retaining compounds and differ chiefly here. THE MAXIMUM IS IN THE PROPERTY'S OWN NAME, which is the pool's settled way of holding a one-sided bound where the value-kind cannot: the b154 `service_temperature_max` shape, and it is why this slot does not have to wait on the standing bounds obligation. Reuses `LengthUnits`; no new machinery. The evidence is Henkel-led and that is stated rather than hidden: the concept is universal in the trade but only one house was found publishing a figure per part number at the mint.
