Well-designed flat metal connection:
- Decorative due to painted large truss head
- Head fits precisely into pre-drilled round holes in metal
- High power transmission when used in applications with shear loads due to integrated underside shaft reinforcement
Can be used universally in outdoor areas that are exposed to weathering - even near lakes - thanks to A4 austenitic stainless steel
Simple to screw in:
- One-handed working due to the tight fit of the RW bit in the screw drive
- Precise positioning, quick engaging and low splitting of the screw due to the ASSY 4 tip with milling ribs
- No over-tightening and high power transmission due to reinforced asymmetrical thread flank geometry
- Easy to screw in due to anti-friction coating
- 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 has limited resistance to acid and is not suitable for atmospheres containing chlorine gas
- We recommend using the Würth software or corresponding design aids for planning and designing your installation. Dimensioning of ASSY screws can be carried out in the Würth timber construction software from a diameter of 5 mm
- ASSY 4, ASSYplus 4 and ASSYplus 4 VG chipboard screws are optimised for use in wood and engineered woods. For applications in plastic anchors where the load 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
Approved in accordance with ETA-11/0190
The requirements of the European Technical Approval (ETA) must be observed.
Datasheets(X)
The painted ASSY 4 A4 TRH gate hinge screw made from high-quality, A4 austenitic stainless steel is ideal for fastening metal profiles for façades or other substructures. The large, rounded truss head and underside shank reinforcement provide a perfect fit in the metal hole.
- ASSY screws are approved for quasi-static loads
- For optimal use of the screw, use the RW bit that fits exactly
