For bolts and screws with metric thread, for uncracked concrete, zinc-plated steel

Minimal effort required to insert anchor

Immediate load-bearing capacity — no waiting

No setting tools required

Can be set flush with surface: Attached parts can be removed/remounted at any time

Triple expansion sleeve to ensure even expansion and load distribution

Suitable for bolts and screws with a metric thread

Applying the specified torque during the anchoring process ensures secure installation

Load-controlled/torque-controlled expanding galvanised steel anchor in sizes M6–M12

Cotter-pin installation

Proof of Performance

ETA-10/0255 for individual attachment, Option 7, non-cracked concrete, galvanised steel, M6–M12; dimensioned in accordance with the European Technical Approval Guidelines (ETAG) for "Metal Anchors for Use in Concrete", Appendix C, measurement process A

Notice

The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of yF = 1.4 have been taken into account. Please refer to the European Technical Approval Guidelines (ETAG), Appendix C, for information on combining tensile and transverse loads, influence of the edge distance and groups of anchors.

The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths.

Compliant with approval if screws and threaded rods with acceptance test certificate 3.1 in accordance with EN 10204:2004 are proven to be the required material and to possess the mechanical properties stipulated in ETA-10/0255

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
04076

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
