Plastic Hexagon Domed Cap Nuts, conforming to DIN 1587 standard, are Hex Nuts that protect the threaded portion of a fastener from damage whilst reducing the risk of injury caused by a sharp or uneven bolt thread.
Often referred to as Acorn Nuts, Crown Hex Nuts, Hex Cap Nuts or Dome Nuts, this component features a raised dome on top – similar to the shape of an acorn.
Found in residential construction or automotive applications, they are typically used to provide an aesthetically pleasing finish and in some cases, increase the performance of an application or assembly.
The raised dome helps to reduce contact with the thread – ideal for situations where shocks or vibrations could result in wear and reduce its lifespan.
Supplied in a White (natural) colour as standard. These Plastic Hexagon Domed Cap Nuts can be dyed in a variety of colours to meet your requirements.
Manufactured from Nylon as standard – a cost-effective material that is strong, lightweight and provides good resistance to water and corrosion.
Available in thread sizes from M4 to M20 as standard, with other sizes available to order. We offer a range of Plastic and Nylon Nuts here at Fastenright.
Non-standard sizes, materials and colours are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
Note: Dimensions may not follow the strict tolerances relevant to metal parts so should be used as guidance only.
