Specification

The self-drilling screw with up to 50% time savings when fastening wood to metal sub-structures

Zinc-plated steel

With self-tapping thread

Countersunk milling head for use with hard and soft woods

AW drive system

Enhanced torque transmission

Longer life

Optimum centring

Better mounting output thanks to fatigue-free screwing in; the required contact pressure for transmission of the torques is considerably lower

Largest possible contact surface of bit in screw drive

Even force distribution prevents damage to the surface-protection coating and therefore ensures better resistance to corrosion

Notice

The recommended maximum wood thickness l_H was calculated with reference to the maximum attachment thickness l_U of the surface!

Wing-pias® screws must be appropriately tested for usability for each application case. Only install using application tools with a depth stop and claw coupling

Drilling screws must be processed with a suitable drill driver (e.g. cordless drill driver with depth stop)

The use of impact screwdrivers is not permitted

Drilling screws must be attached perpendicular to the surface of the component

For 3.9/4.2/4.8 mm ∅

General construction permit Z-14.4-634

For use with wood and gypsum material boards and cement-bound mineral construction material boards with thin-walled steel profiles.

Drilling screws may only be used where dampness is not to be expected. For connection elements with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.

Application

Instructions

Force feeding of the screw is prevented by the wings drilling out the wood

The core hole is drilled into the substructure. The wings break off upon contact with the metal

The first few turns of the screw cut the thread, the remainder of the screw then screws into the thread

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
