Easy installation with cordless drill. Avoids hitting reinforcement due to very low insertion depth. For concrete, with connecting thread, ideal for mounting pipe clamps or spacer sleeves, zinc plated steel
  • Quick and easy installation without the need for a tangential impact screwdriver

  • Time and cost-saving assembly

  • Only requires a 30 mm drill hole depth – no need for reinforcements

  • Can be assembled by hand
Proof of Performance
  • ETA-15/0091 for anchors in a redundant non-structural system made from concrete

  • Fire resistance: R30, R60, R90, R120; Technical Report TR020
Notice
  • The W-BS Compact can be mounted by hand

  • If a cordless drill is used for assembly, it is recommended that at least five preliminary tests are performed on location to ensure the correct drill driver setting and to prevent over-tightening of the W-BS Compact. It is recommended that you start with the drill driver's lowest torque setting and increase it if necessary

  • A tangential impact driver must not be used for assembly

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

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
