Spec search

Search parts by specification, in one set of units

The search a specifying engineer actually runs, instead of the keyword search a directory usually offers.

Every supplier maps their own attribute onto the shared spec, so the millimetres mean the same thing on all three rows.

Why the units are the hard part

Two suppliers both listing a “Diameter” of 10 are not describing the same part if one means millimetres and the other inches. Specifications are therefore defined once by the platform with a fixed unit, and each supplier maps their own axis onto one with a conversion factor. The stored value is always in the canonical unit, so a range filter compares like with like.

Variable products are searchable through their variants

A fastener family carries its diameters on the variants rather than the parent, so searching a diameter finds the family through them. Unpublished variants are excluded, which means a draft size cannot make a product answer a filter it should not.

A filter that cannot quietly mislead

Asking for a specification a product does not carry excludes it rather than being ignored. The alternative returns parts that look qualified and are not, and nobody double-checks a spec search they trust.
