20mm Threaded M5 Hole ABS Ball Knob

These Shiny Round Ball Knobs come with either a Female Thread or a Plain Sided Boss and are suitable for a whole host of applications and it's important to note that the Dimensions listed, refer to the Approx. Diameter of the Ball by the Threaded Boss.  The threaded inserts are typically a Thread within the Plastic itself or a Metal Threaded Insert which is either a Brass or Zinc Construction.

This particular ball knob is a cored out design manufactured from ABS, so wouldn't be suitable for extreme conditions, where excessive stress needs to be endured. For particularly heavy duty applications, we'd recommend a solid Duroplast ball knob, which are also listed on our site.

Most of these parts have a Gloss finish and are made from ABS or Polypropylene, although we do have some models produced in with a Matt Finish, just check with Sales if you're unsure. We show standard colours & finishes where possible but these are constantly changing so if you require a colour not listed in the drop-down, speak to us as we may well have added it since.
