The hammer-head screws with serration have been specially developed for use with mounting rails.

Steel.

Hot-dip galvanised.
Grade 8.8

The serrated hammer-head screw can be inserted into the mounting rail at any point. By turning it through 90°, the rounded head of the screw grips securely in the slot and prevents it from twisting. The special toothing of the hammer head ensures a highly stable and resilient connection, even when mounted vertically. The hammer-head screw can be positioned anywhere in the slot of the mounting rail, permitting for flexible positioning. A slot in the end of the thread indicates the correct alignment of the screw head in the mounting rail.

The large contact area of the screw head in the mounting rail ensures high stability and load-bearing capacity.

Suitable for System 41 mounting profiles (41/22 and 41/41).

Observe the profile permissible load As a rule, the permissible loads for mounting rails are lower than those for screws.
