Material & Tolerance
The standard material is listed below; also available in steel, stainless, brass and aluminium. Dimensions in mm; tolerances machined to ISO. Deviations (mm) are given for the nominal diameter according to the ISO 286-2 tables; thread tolerances (6g/6H) are to ISO 965. For custom sizes/tolerances, contact us with the part code.
Manufacturing Scope
Standard Hex Nut is a Nuts & Adapters family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀6.4–19.6 mm, lengths 1.6–10 mm, standard material Steel (also stainless steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is SOMA-ARA-12 at 10 mm. Besides turning, the family requires hex flat milling (AF 5.5–17). Bores in this family run ⌀2–12 mm. All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is SOMA-ARA-12: 10 mm long at ⌀19.6 mm, L/D 0.5. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to 6H tolerance; the smallest is SOMA-ARA-02 (⌀6.4 mm) and the largest SOMA-ARA-12 (⌀19.6 mm). The family includes hex-drive, bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
