An Insert for use inside the end of round and square section
The Crown-nut is a revolutionary solution for the creation of a strong
reusable female thread at the end of round or square section tubes. Crown-
nut solves the issue of how to securely fix to the end of round or square
section, guaranteeing superior torque-out and pull-out performance. The
product range offers solutions for round tube and square section and is
available in a wide range of sizes. A version is also available that is designed
to accept push-fit castors. Specials to suit your design can be made to
order.
Advantages of the Crown-nut
•
Can be installed into square section with a wide internal size
tolerance range. Thanks to the flexibility of the crown design, the
same item code can be used for a range internal sizes.
•
The crown is designed so that the shape of the tube section is not
altered during installation, guaranteeing the aesthetics of the external
surface.
•
Crown-nuts are easy to install and are cost effective. The press-in fit is
fast and easy, enabling the elimination of traditional and costly
assembly processes such as welding and staking.
Note
After the insertion of the Crown Nut avoid heat treatments, galvanization
and other heating operations that could compromise the characteristics of
the product.
