BS EN ISO – Fasteners. Hot dip galvanized coatings

This tapping leaves the internal threads exposed not covered with zincbut it has no detrimental effects on the corrosion resistance, as illustrated further below. Need more than one copy? As the voice of the U. The process of hot dip galvanizing is quite simple: We have no amendments or corrections for this standard. Your shopping cart is empty. It provides a very solid and durable corrosion protection.

Your Alert Profile lists the documents that will be monitored. This standard is also available to be included in Standards Subscriptions. In case the zinc coating is scratched or chipped, the zinc cin attempts to cover the damaged area in normal atmospheric environments. If the document is revised or amended, you will be notified by email.

The zinc layer on the bolt thread completely overtakes the protection of the uncoated nut thread. 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.

Nuts are processed in the same ej, except the nut thread is not yet formed. Please first log in with a verified email before subscribing to alerts.

HOT DIP GALVANIZING

We have no amendments or corrections for this standard. Subscription pricing is determined by: 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 djnwhich is called the oversize HDG system.

Polski English Select Language: A white, voluminous zinc corrosion product, “white rust,” may develop, though this product may be less desirable for reasons of aesthetics or painting. The nut oversize limits are standardized in ISOand the thread tolerance class of the oversize tapped nuts is designated as 6AZ. Next, the fasteners are spun to remove the excess zinc, and then they are cooled in water to solidify the zinc.

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.

Due to the deviation of the thread tolerances, the screw thread of the bolt is allowed to strip at the minimum ultimate tensile load. Please first verify your email before subscribing to alerts.

Hot dip galvanizing for steel parts iiso standardized in ISObut for fasteners, the dedicated standard ISO exists. Already Subscribed to this document.

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.
