Flat washer with chamfer for high-strength fittings

“Only use complete fitting sets from one manufacturer (bolts, nuts and washers)”.

The design of steel structures with high-strength fittings is regulated by DIN EN 1090-2 and DASt directive 024.

Due to batch traceability, these articles can only be purchased from and stored directly by the manufacturer and are therefore excluded from exchange or return!

Storage and transport:

Screws, nuts and washers are supplied in a hot-dip zinc-plated version with nut lubricated under process conditions. The female thread of the nut is not hot-dip zinc-plated and is protected against corrosion solely by the applied lubrication. Improper transport and storage conditions can result in corrosion of the female thread or to a change in the lubrication condition as supplied and the correlation between tightening torque and pretensioning force associated with this.
