It is a suitable solution in very aggressive atmospheres e. The other solution provided by ISO is to tap the internal threads nuts to be a bit larger oversize so that they mate with the galvanized externally threaded fastener boltwhich is called the oversize HDG system. We have no document history for this standard. 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.

Hot dip galvanizing for steel parts is standardized in ISObut for fasteners, the dedicated standard ISO exists. Please first verify your email before subscribing to alerts. In case the zinc coating is scratched or chipped, the zinc layer attempts to cover the damaged area in normal atmospheric environments.

Please first log in with a verified email before subscribing to alerts. The standard specifies material, procedure, dimensions and some performance requirements for hot dip galvanizing of fasteners made of steel with thread. As the voice of the U. At locations where there are gaps in the zinc layer of 1. A so called duplex system is a combination of hot dip galvanizing and painting.

Nuts are processed in the same way, except the nut thread is not yet formed. Standards Subsctiption may be the perfect solution.

When the coating is exposed to the atmosphere, a layer of corrosion products zinc patina is built up. This standard is not included in any packages. The process of hot dip galvanizing is quite simple: Nederlands English Select Language: We have no document history for this standard.

Your Alert Profile lists the documents that will be monitored. This layer primarily consists of zinc carbonate, which, because it is almost insoluble, delays further corrosion. This standard is also available to be included in Standards Dij. 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. Because zinc is less noble than iron steelthe zinc dissolves first, which protects the steel against corrosion until all of the zinc has dissolved. We have no amendments or corrections for this standard.

If the document is revised or amended, you will be notified by email. Dutch English Select Language: When galvanized, steel remains wet for a longer period, and there is insufficient air circulation.

It provides a very solid and durable corrosion protection. In order to cope with this issue, ISO provides two solutions, both of which involve changes in the dimensions of the basic threaded fasteners.

The formation of white rust can be suppressed by appropriate storage and packaging or, if necessary, by oiling the zinc or passivating fin in chromic acid. A white, voluminous zinc corrosion product, “white rust,” may develop, though this product may be less desirable for reasons of aesthetics or painting. We have no amendments or corrections for this standard.

HOT DIP GALVANIZING

The large amount of zinc provides excellent corrosion resistance in normal outdoor environments, but with the downside that its layer thickness is significantly above the thread clearance allowance, which this poses a problem for all di fasteners. Next, the fasteners are spun to remove the excess zinc, and then they are cooled in water to solidify the zinc. Need more than one copy? An example of this phenomenon is the screw thread of hot dip galvanized nuts that are tapped after galvanizing.
