5 Series Flat Head - STET Aesthetic Architectural Tamper Resistant Screw
The STET range of self-drilling screws provides a perfect solution for applications that require a more aesthetic architectural appearance at the fixing point. The low-profile round Flat head is achieved by use of a special installation tool that clamps the fastener from under the head consequently offering tamper resistant benefits.
This STET screw is equipped with a specialty 5 series self-drilling point (4.00 to 12.00MM steel drilling capacity), fine thread and has a class 4 mechanically galvanised finish.
Many high-quality cladding projects are often compromised by use of painted hexagon headed screws that get damaged easily on installation. STET screws can be painted to colour match as required and be assembled with a bonded EPDM washer that ensures the fixing system is of the highest integrity and appearance while offering security benefits at the same time. Available in mechanically plated class 4 coating and on special request in 304 or 316 grade stainless steel versions. STET screws are manufactured in Italy.
