When the coating is exposed to oso atmosphere, a layer of corrosion products zinc patina is built up. It provides a very solid and durable corrosion protection.
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.
As the voice of the U. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The nut oversize limits are standardized in ISOand the thread tolerance class of the ej tapped nuts is designated as 6AZ. Generally, it can be stated that the mechanical properties of the bolts in accordance with ISO and the nuts in accordance with ISO are not influenced by hot dip galvanizing.
Sin case the zinc coating is scratched or chipped, the zinc layer attempts to cover the damaged area in normal atmospheric environments. This ddin should be consulted only for rough estimates due to unforeseeable local influences.
Dinn Alert Profile lists the documents that will be monitored. Subscription pricing is determined by: This tapping leaves the internal threads exposed not covered with zincbut it has no detrimental effects on the corrosion resistance, as illustrated further below. The formation of white rust can be jso by appropriate storage and packaging or, if necessary, by oiling the zinc or passivating it in chromic acid. Proceed to Checkout Continue Shopping.

The HDG process is commonly regarded as suitable for fasteners with diameters M8 or larger. Standards Subsctiption may be the perfect solution. Please first verify your email before subscribing to alerts. The zinc layer on the bolt thread completely overtakes the protection of the uncoated nut thread.

This standard is also available to be included in Standards Subscriptions. Magyar English Select Language: The standard specifies material, procedure, dimensions and some performance requirements for hot dip galvanizing of fasteners made of steel with thread. At locations where there are gaps in the zinc layer of 10648. Dutch English Select Language: Nederlands English Select Language: Nut threads must always be tapped after HDG.

What remains is a layer of zinc 40 to 70 microns on the surface of the products that is relatively thick compared to zinc electroplating 3 to 20 microns. One solution is a system in which the externally threaded fasteners bolts are manufactured with a larger fundamental deviation such that the thread is made slightly thinner.

The two systems must never be mixed, as mixing leads either to fitting problems oversized bolt with ISO fit nut or critical strength reductions of the threaded connection ISO fit bolt with oversized nut.
