For threaded rods, threaded fittings etc., for concrete

Stop bits must be used

Anchors and stop bits form a perfectly coordinated system. This system unit prevents installation errors and ensures attachment as stipulated in the approval.

Small drill hole depth

Small drill hole diameter

Low minimum component thickness (h_min = 80 mm)

Immediate load-bearing capacity – no waiting after insertion

Easy insertion — no installation torque

Anchorage via friction locking – distance-controlled expanding anchor

Proof of Performance

Multiple attachment of non-load-bearing systems in concrete: European Technical Approval ETA-07/0138

Dimensioned in accordance with the European Technical Approval Guidelines (ETAG) for "Metal Anchors for Use in Concrete", Appendix C, measurement process C

Fire resistance (anchoring base: concrete C20/25 to C50/60): R30, R60, R90, R120 (W-SD M6L, W-SD M8): Technical Report TR 020 "Evaluation of anchorages in concrete concerning resistance to fire" (included in ETA-07/0138)

Notice

The partial safety factors of the resistances regulated in the approval and a partial safety factor of the effects 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, edge influence and groups of anchors.

The partial safety factors for load-bearing capacity on exposure to fire of yM,fi = 1.0 as recommended in the approval and the partial safety factor of the effects of yF = 1.0 have been taken into account.

Carbide masonry drills must comply with the specifications set out in the code of practice of the German institute of building technology (DIBt) and the Association of German Tool Manufacturers (FWI) on the characteristics, requirements and tests of masonry drills with carbide cutting inserts used to drill holes for fixing anchors. Würth hammer drills meet the specifications set out in the code of practice.

Application area

Can be used for multiple attachment of non-load-bearing systems in concrete, anchorage of lightweight ceiling cladding and suspended ceilings

Multiple attachment of non-load-bearing systems: Anchorage with European Technical Approval in cracked concrete (tension zone) and non-cracked concrete (compression zone)

The anchor has European Technical Approval for use in reinforced or non-reinforced standard concrete with a strength class of min. C20/25 and max. C50/60 in accordance with EN 206:2000-12

The anchor may be used for anchorages with predominantly static loads or quasi-static loads

W-SD (galvanised steel) can be used in dry indoor areas

Suitable for attaching ceiling structures with threaded rods, suspension of threaded rods, cable and pipe clamps, cable and ventilation ducts etc.

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
