Knurled Contact
Press-fit contact with knurled body; the knurl prevents rotation and pull-out in the plastic housing.

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
Knurled Contact is a Connector Pins family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀1.8–13.6 mm, lengths 18–66 mm, standard material Brass (also steel, stainless steel 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 ⌀14 mm bar stock; its longest variant is KONA-KNR-12 at 66 mm. Besides turning, the family requires knurling. All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is KONA-KNR-15: 18 mm long at ⌀1.8 mm, a length-to-diameter ratio of 10.0. This ratio is the very reason sliding-head lathes exist. The guide bushing supports the bar immediately beside the cutting point, so there is no deflection; the same part chatters and drifts in diameter on a conventional lathe.
Variants are machined to h9 tolerance; the smallest is KONA-KNR-15 (⌀1.8 mm) and the largest KONA-KNR-12 (⌀13.6 mm). The family includes knurled, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
