Partial-thread screw made of high-quality austenitic A2 stainless steel with visually appealing pan head for fastening metal hollow profiles in wood in outdoor areas exposed to the elements

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

Flat fastening metal sheets for secondary purposes

Flat, cylindrical head rounded with a lens

Large surface contact area

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

Stainless mounting for accessible wood connections in outdoor areas exposed to weathering

Made of austenitic, non-magnetic and non-rusting A2 stainless steel

Can be used in rural or urban environments or industrial atmospheres without significant exposure to chlorides or SO₂

With friction-reducing slide coating for easy fastening

Notice

Austenitic stainless steel is characterised by a high degree of corrosion resistance against aggressive industrial air, sea air, tap water, river water, mine water and salt water, as well as woods containing tannic acid. It is resistant to acid to a certain extent and not suitable for atmospheres containing chlorine gas

We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Use the Würth timber construction software for dimensioning of ASSY screws from a diameter of 5 mm

ASSY 4, ASSYplus 4 and ASSYplus 4 FT chipboard screws are optimised for use in wood and wood materials. For applications in plastic anchors where load capacity can also be reduced, use only screws without an optimised thread tip (tip with milling ribs, drill tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head

Application area

For wood-wood connections designed to pull together

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

Instructions

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

If countersunk head screws are used for a metal-to-wood mounting, the metal to be connected must be provided with suitable countersunk holes

For a load-bearing wood-metal connection, ASSY screws must be tightened to a specific torque value. Tightening torque = required prevailing torque x 1.2 < 90% of the breaking torque

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:
