High-strength preloadable fittings for bolted connections in metal constructions


  • HV system

  • K1 class

  • Strength class 10.9

  • Hot-dip galvanised steel


High-tensile prestressed bolts with large width across flats:


Large under-head surface


  • Reduced surface pressure

  • Reduced setting


Large under-head radius


  • Reduced notching effect

  • Better long-term resistance to vibration


Defined friction properties


  • Enables planned preloading


Lot marking on the product


  • This omits the need to request test certificate 3.1 in accordance with EN 10204. (see tab. 1 DIN EN 1090-2:2018-09)


CE marking


  • Controlled construction product
Notice

The design of supporting steel structures with high-strength fittings is regulated by DIN EN 1090-2 and DASt directive 024. “Only use complete fitting sets from one manufacturer (bolts, nuts and washers)”.



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.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
