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
Hex Standoff F/F (Female-Female) is a Spacers & Standoffs family precision-turned on a Goodway SW-20, covering 12 variants — diameters ⌀6.4–15 mm, lengths 10–50 mm, standard material Stainless Steel (also 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 ⌀16 mm bar stock; its longest variant is ARAB-HFF-12 at 50 mm. Besides turning, the family requires hex flat milling (AF 5.5–13) and axial drilling (⌀2.5–6.8 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 ARAB-HFF-06: 35 mm long at ⌀8.1 mm, L/D 4.3. This ratio is achievable on a conventional lathe as well; the sliding-head advantage in series work is that the part never leaves the machine, so the size does not drift from variant to variant.
Variants are machined to 6H tolerance; the smallest is ARAB-HFF-01 (⌀6.4 mm) and the largest ARAB-HFF-12 (⌀15 mm). The family includes hex-drive, bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
