High-quality partial-thread screw made of high-quality austenitic HCR stainless steel 1.4529 with countersunk head for wood-wood fastening in areas constantly exposed to corrosion, swimming pool area (corrosion resistance class V)

Ideal power transmission thanks to RW drive


  • More power due to larger contact area at the bit

  • More stability, one-handed working, precise positioning due to the tight-fit recess and perfect fit of the bit

  • Fewer bit changes, one bit for many screw diameters

  • Compatibility with previous AW drive


Form-fitting connection to metal fittings or in wooden products with high bulk density


  • For fitting connection with full-thread steel screws

  • Perfect fit of 90° head in fitting parts with metal countersinks

  • Pulls together without head milling due to lack of milling elements below the head

  • The head is inserted by pressing


Higher breaking torque


  • Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the single thread

  • Better anchoring thanks to higher thread flanks


Smooth thread start ensures optimised recessing and biting of the screw


  • Reduced splitting effect due to displacement effect of the dome-shaped milling elements in the tip

  • Friction-reduced thread rotation allows reduction of the screw-in force to be applied


Suitable for extremely chlorine-laden areas, with simultaneous SO2-, exposure to chlorine gas and high temperatures


  • Made of high corrosion-resistant, austenitic, non-magnetic and non-rusting stainless steel, class HCR (high corrosion resistant) 1.4529

  • Can be used in outdoor areas exposed to the elements, areas with spray water or foggy areas or industrial atmosphere with extreme chlorides exposure at simultaneous elevated concentrations of SO2 or chlorine gas and high temperature and with significant concentration of pollutants in the absence of cleaning, e.g. swimming pool or tunnel construction

  • Corrosion resistance class KWK V
Notice
  • ASSY screws are approved for quasi-static loads

  • For optimum use of the screw, the right-size RW bit must be used

  • Partial-thread screws are ideal for connecting wooden components. To achieve optimum assembly of the components, the components to be fixed must not be thicker than the length of the shank

  • To avoid contact corrosion that can occur between two different metals in direct contact. The noble metal promotes, in conjunction with e.g. water or normal humidity, corrosion of the base metal. It is generally recommended that the product with the smaller surface area, e.g. the screw, be made of the noble metal. A shielding non-conductive layer between the metals is also recommended

ETA-11/0190 approved

The requirements of the European Technical Approval (ETA) must be observed

Application area

For wood-wood connections designed for combination in areas constantly exposed to corrosion


The partial thread starting immediately below the shank allows for wood-wood connections designed to pull together. The screw thread is positioned entirely in the lower component once screwed in.



Can be used for outdoor applications and utilisation class 3

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
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
