Tapered Thread Transition Adapter
Transition adapter with a centering tapered body and an external thread at the tip.
Manufacturing Scope
Tapered Thread Transition Adapter is a Nuts & Adapters family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀8–20 mm, lengths 19–40 mm, standard material Stainless Steel (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is SOMB-KDA-10 at 40 mm. Besides turning, the family requires thread turning (6 sizes from M4 to M12) and taper turning. 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 SOMB-KDA-02: 23 mm long at ⌀9 mm, L/D 2.6. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to 6g tolerance; the smallest is SOMB-KDA-01 (⌀8 mm) and the largest SOMB-KDA-10 (⌀20 mm). The family includes threaded, tapered, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
This is a dimension schematic, not a manufacturing drawing. Dimensions match the catalog data; request a quote with the part code to confirm before production.
