High-quality partial-thread screw made of high-quality austenitic HCR stainless steel 1.4539 with countersunk head for wood-wood fastening in areas severely exposed to corrosion (corrosion resistance class IV)

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 high chloride or SO₂-contaminated areas with simultaneous exposure to splash water or fog

Made of high corrosion-resistant, austenitic, non-magnetic and non-rusting stainless steel, class HCR (high corrosion resistant) 1.4539

Can be used in outdoor areas exposed to the elements, areas with spray water or foggy areas or industrial atmosphere with a high level of chloride exposure at simultaneous elevated concentrations of SO₂ and high humidity and with significant concentration of pollutants

Corrosion resistance class KWK IV

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 to pull together in areas severely 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
