For requirements beyond the tabulated combinations, enquire about aluminium, brass, nylon, duplex, superduplex or an ASTM specification. Alloy or grade, dimensions, mechanical requirements and finish are defined for the enquiry; the geometric reference does not automatically imply conformity with the product standard.

Select the finish for the material/property-class combination. Hydrogen relief and lubrication are separate process requirements, not certificates and not implied by the coating name.
ISO, DIN and UNI: key differences
ISO 4033:2023
Related commercial series with its own geometry. Examples: M10 has 17 mm flats in the commercial UNI series and 16 mm in ISO; M16 is 16 mm high in UNI and up to 16.4 mm in the ISO selection. Compare before substitution.
