Threaded Sleeve (Round Coupler)
Round-body threaded sleeve with internal thread that couples threaded rods on a smooth outer surface.
Manufacturing Scope
Threaded Sleeve (Round Coupler) is a Nuts & Adapters family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀6–18 mm, lengths 15–35 mm, standard material Brass (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 ⌀18 mm bar stock; its longest variant is SOMA-KOV-10 at 35 mm. Besides turning, the family requires knurling and axial drilling (⌀3–10 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-KOV-03: 15 mm long at ⌀6 mm, L/D 2.5. 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-KOV-03 (⌀6 mm) and the largest SOMA-KOV-10 (⌀18 mm). The family includes knurled, bored 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.
