Key Features
1. Good corrosion resistance - A2/A4 stainless steel stands up well in coastal areas, chemical plants and other harsh working conditions.
2. Flush installation - the countersunk head sinks fully into the hole, leaving a smooth surface with nothing protruding.
3. Reliable driving - the hex socket takes the wrench firmly, so tightening is stable and the driver is less likely to slip or strip.
4. Standard dimensions - made to DIN 7991 / ISO 10642, fully interchangeable with other brands of the same standard.
5. Solid strength - cold-forged blanks give consistent, dependable quality batch after batch.
Typical Applications
- Machinery: precision equipment assembly where a flush surface is required.
- Marine & Outdoor: fittings and structures exposed to salt water and weather.
- Automotive: engine components and body panel mounting.
- Architecture: decorative metal work where visible screw heads are not acceptable.
- Electronics: fixing chassis and covers without anything sticking out.
