Hex Drive Coupling Adapter

Coupling adapter with a bored cylindrical body and hex drive end turned by a spanner.

Manufacturing Scope

Hex Drive Coupling Adapter is a Couplings & Shaft Adapters family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀11.5–19.6 mm, lengths 20–37 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 KAPA-HKA-11 at 37 mm. Besides turning, the family requires hex flat milling (AF 10–17). Bores in this family run ⌀3–11 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 KAPA-HKA-04: 22 mm long at ⌀11.5 mm, L/D 1.9. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.

Variants are machined to H7 tolerance; the smallest is KAPA-HKA-03 (⌀11.5 mm) and the largest KAPA-HKA-11 (⌀19.6 mm). The family includes hex-drive, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
