Zinc-plated steel, blue passivated, full thread, tapered head, AW drive, roller-sorted
Joins wood without causing cracks
Special flat conical head, ∅ 7.2 mm, with luminous lens and braking ribs under the head
- Thanks to the special shape of the head, it fits the shape of the connector
- With the braking ribs under the head, the screws can be prevented from turning in the connector
AW machine drive system
- Improved power transmission
- Longer service life
- Optimal centring
- Largest possible contact surface
Thread
- Asymmetrical, single-phase thread with sharp tip for fast action.
- Minimal splitting forces, especially when turning on the edges. The risk of cracking is eliminated by the use of an annular thread
- The low tightening torque extends the life of the machining machine and the insert.
Large pack
Sturdy, large cardboard box with handle and chute. Ideal for filling machines.
Zinc plated screws are not suitable for use outdoors or in areas of high humidity! In such cases, use ASSY® 3.0 screws made of A2 stainless steel.
In order to fix metals to wood, a precise cut-out must be made in the metal plate using a flat awl.
ASSY 3.0 chipboard screws have been optimally adapted for use in wood. A reduced load-bearing capacity of the connection must be considered when using these screws for plastic dowels. For this reason, we recommend using only screws without optimised thread end (drill, counter-thread, ring thread, serrated edge, discharge groove, etc.) in the dowels, e.g. Würth ASSY D, prefix 0151 (flat tapered head) and prefix 0153 (pan head).
ETA-11/0190
ETA-11/0190 approval must be observed when using these screws.
