FISCHER Hammerfix N:N 5 x 40/15 S

The FISCHER Hammerfix N:N 5 x 40/15 S is a heavy-duty nail specified for secure installation in masonry substrates. It features a nominal diameter of 5 mm and a total nominal length of 40 mm, with a designated embedment depth of 15 mm. These dimensions are engineered to provide reliable holding power when driven into concrete or solid brick. Buyers select this fastener for structural anchoring tasks that demand high load-bearing capacity and resistance to vibration. When choosing this specific size, ensure the substrate thickness supports the 15 mm embedment depth while maintaining adequate edge distances and spacing according to local structural codes. This product is distinct from lighter-duty anchors as it relies on the full penetration of the 40 mm shank to achieve its performance rating.
