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
Knurled Adjusting Nut is a Fixing & Locating family precision-turned on a Goodway SW-20, covering 12 variants — diameters ⌀10–20 mm, lengths 8–22 mm, standard material Aluminium (also steel, stainless steel or brass). 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 TESB-TAS-M10S at 22 mm. Besides turning, the family requires hex flat milling (AF 10–13), knurling and axial drilling (⌀2.5–8.5 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 TESB-TAS-M8H: 20 mm long at ⌀18 mm, L/D 1.1. 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 TESB-TAS-M3 (⌀10 mm) and the largest TESB-TAS-M10S (⌀20 mm). The family includes hex-drive, knurled, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
