Standards Subsctiption may be the perfect solution. The nut oversize limits are standardized in ISOand the thread tolerance class of ej oversize tapped nuts is designated as 6AZ. Further specific values can be found in DIN Another important aspect of cathodic protection is that no corrosion occurs underneath the zinc layer.
This standard is not included in any packages.

Nederlands English Select Language: Please first log in with a verified email before subscribing to alerts. Nuts are processed in the same way, except the nut thread is not yet formed. When galvanized, steel remains wet for a longer period, and there dib insufficient air circulation. Proceed to Checkout Continue Shopping.
Please first verify your email before subscribing to alerts. An example 100684 this phenomenon is the screw thread of hot dip galvanized nuts that are tapped after galvanizing. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. The standard specifies material, procedure, dimensions and some performance requirements for hot dip galvanizing of fasteners made of steel with thread.

This standard is also available to be included in Standards Subscriptions. The zinc layer on the bolt thread completely overtakes the protection of the uncoated nut thread.
Magyar English Select Language: A so called duplex system is a combination of hot dip galvanizing and painting. Please refer to EN for details. When properly degreased, hot dip galvanizing offers effective adhesion for many types of paint.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This tapping leaves the internal threads exposed not covered with zincbut it has no detrimental effects on the corrosion resistance, as illustrated further below.
Generally, it can be stated that the mechanical properties of the bolts in accordance with ISO and the nuts in accordance with ISO are sio influenced by hot dip galvanizing.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. We have no amendments or corrections for this standard. A white, voluminous zinc corrosion product, “white rust,” may develop, though this product may be less desirable for reasons of aesthetics or painting.
The time that steel remains protected from corrosion is proportional to the thickness of the zinc layer, and it is dependent on the climatic conditions, as shown in the graphic below. We have no document history for this standard. Subscription pricing is determined by: In case the zinc coating is scratched or chipped, the zinc layer attempts to cover the damaged rin in normal atmospheric environments.
