Protects the attachment screws against bending and cutting strains
This gives extra security
Less screws, lower building height. RUD-specialty screws (internal + external hexagon)
100% crack tested with special corrosion protective Deltaton
Tighten the bolt (120 Nm) with subjected security plates
To seal the bolts it is possible to for example use Loctite 270
Check at regular intervals that the screws are in place
Screwing material minimum 1.0037 (St 37-2) S235JR
Follow the user manual.
Only use RUD specialty bolts
Ensure that you have an even screwing surface
Screwing and drilling acc. area of tolerance for VRBG:
1. First make a hole and lower relief drilling measures “F” and equivalent measures “H, G, K”
2. After adaption and adjustment of screw-on block the thread hole can be drilled
3. Drill the core hole and make threads
For through-door bolts only drill with measure “H”
Patented relief pipes
With VRBG 10 and 16, the attachment bolts protect against bending and cutting strains
This gives extra security
Less screws, lower building height
Holes and drills acc. area of tolerance VRBG
Favorable distribution of power
Supplied hexagon screws are 100% crack tested
Screwing material 1.0037 (St 37-2) S235JR
Check at regular intervals that the screws are in place
For light alloy and castings a thread arrangement must be chosen so that carrying capacity of the thread is equivalent to the requirements for the relevant basis material
