## Long description

Koelner DIN 933 hex head full-thread screw 6×20 mm in A2 stainless steel is a metric fastener designed for general-purpose assembly where a fully threaded shank and a hexagonal head are required. The screw conforms to DIN 933 geometry with full threading along the shank and a standard hex head suitable for wrench or socket driving. Made from A2 stainless steel, it provides corrosion resistance for indoor and outdoor applications in metal, wood and plastic components. The product is supplied as a pack of 6 pieces for repair, maintenance or small assembly tasks.
Advantages
The A2 stainless steel construction ensures good resistance to corrosion and staining in common atmospheric conditions. Full-thread design allows for secure clamping and easy adjustment along the entire length of the shank, while the hex head provides reliable torque transfer with standard hand tools or power sockets. A compact 6×20 mm size offers a balance between strength and minimal protrusion for installations where space is limited.
Suitable for
Fastening thin metal sheets and frames
Securing wooden components and fixtures
Assembly and repair of plastic housings and parts
Small machinery and equipment maintenance
General household and DIY projects requiring corrosion resistance
Key specifications
Type: Hex head full-thread screw (metric)
Thread: Full thread along shank
Size: 6 × 20 mm (nominal diameter × length)
Material: A2 stainless steel (corrosion-resistant grade)
Drive: Hexagonal head suitable for wrench or socket
Pack quantity: 6 pieces
How to use
Select an appropriate pilot hole or mating tapped hole matching the nominal 6 mm diameter and material being joined. Position the screw so the full thread engages the mating part and apply torque using a suitably sized wrench or socket until the required clamp force is achieved. For wood or thin metal where a nut will be used, ensure the mating nut and washer are compatible with A2 stainless steel to avoid galvanic issues. For through-fastening, verify protrusion clearance on the opposite side before final tightening.
Usage recommendations
Use standard hex sockets or wrenches sized for the DIN 933 hex head and avoid overtightening to prevent thread or head damage. When fastening dissimilar metals, consider using compatible washers or protective coatings to minimize galvanic corrosion. Store screws in a dry environment to preserve stainless steel finish and ensure consistent performance.
