Available Brands:
- Fischer – Known for precision and performance in concrete fixings
Applications:
Ideal for bracketry, base plates, support frameworks, and threaded rod anchoring. These screws provide a secure hold without causing expansion stress, making them suitable for edge fixing and reduced embedment depths.
