Field of Application:

For HV connections in steel structures

Advantages:

• Large under-head surface for lower surface pressure
• Large under-head radius for reduced notching effect
• Defined friction properties facilitate planned pre-tensioning
• Lot marking on the product means no need to request acceptance test certificate 3.1
• (see table 1 DIN EN 1090-2:2011-10)
• CE marking - Regulated construction product

Design:

With large wrench size

Advice:

Only use complete fitting sets from one manufacturer (1 bolt, 1 nut, 2 washers). Products in accordance with the new European
product standards EN 14399-4 and EN 14399-6 with CE marking replace the applicable domestic products to DIN 6914 et seq. with the German quality mark.
