Specification

Special partial-thread screw made of high-quality, austenitic A4 stainless steel with small, raised countersunk head and milling ribs for visually appealing fastening close to edges, without pre-drilling, of wooden façades, skirting boards, fences etc. in outdoor areas constantly exposed to weathering

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

Precise positioning and very clean drilling due to advanced centring drill tip

Positioning and drilling without chipping

Maximum drilling performance and precise drilling process through drilling cutting edges (similar to Forstner bit)

Precise positioning on hard surfaces without slipping thanks to centring pin

Quick screwing due to gentle start of thread

Easy countersinking in softwoods and hardwoods

Visually appealing connections due to lens-shaped, rounded head

High milling power and chip collection for clean countersinking of the head in softwood/hardwood

For universal use in wood and metal connections due to milling pockets integrated in the countersunk head

Can be combined with 90° metal countersink

Maximum reliability of the screw connection

Asymmetrical single thread

Through optimal matching of drill tip and thread geometry

Excellent anchoring in wood due to asymmetrical arrangement of thread flanks

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

Made of austenitic, non-magnetic and non-rusting A4 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 screwing

Notice

We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Dimensioning the ASSY screws can be carried out in the Würth timber construction software from a ∅ 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 bit tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head

Application

Application area

For wood to wood connections designed to pull together

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

Instructions

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

ASSY screws are approved for quasi-static loads

ASSY stainless steel screws can be used to attach hard wood decking and flooring. Pre-drilling is recommended for tropical timber with high bulk density

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 v

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
