20mm Push Fit Stainless Steel Ball Knob – 6mm H7 Hole – A2 Stainless Steel

Featuring a 20mm diameter and a 6mm H7 H7 hole, this A2 Stainless Steel ball knob is suited to workshop fixtures. The push fit design provides a rounded termination on a suitably sized shaft.

What Are Stainless Steel Ball Knobs?

Push-fit stainless steel ball knobs are spherical fittings with an unthreaded hole designed to fit a matching shaft. This version has a 6mm H7 H7 hole and a listed insertion depth of 12.0mm; the mating shaft must be checked for suitability before fitting. The knob provides a hand contact without a threaded fastening.

Common Applications

  • Equipment panels: Completes a protruding control handle on machinery or an instrument assembly. Check the 6mm H7 H7 hole against the mating part.
  • Lever ends: Provides a rounded hand contact at the end of a compatible operating lever.
  • Cabinet fittings: Creates a compact grip on compatible furniture or enclosure hardware.
  • Control mechanisms: Finishes a shaft or lever used for manual operation.
