FM 753 is a heavy duty expansion anchor which is used for Higher tension loading applications.
It is also called with different names like stud anchor, expansion anchor, wedge anchor.
FM 753 comes with three different type of materials.
1) Stainless Steel A4 Grade - Stainless steel threaded rod with A4-70 Grade.
2) 5.8 grade Carbon Steel with Nautilus Coating - Higher grade carbon steel with a special Nautilus coating of 10 microns which can withstand 1000 hours of salt spray test.
3) 5.8 grade carbon steel with Zinc Coating - Higher grade carbon steel with minimum 5 microns of zinc coating applied through electro plating to prevent from corrosion.

(1)
The design loads Nrd
and Vrd
derive from the characteristic loads on the ETA certification and are inclusive of the partial safety factors gm
proportional to each diameter (see ETA).
(2)
The recommended loads N and V derive from the characteristic loads on the ETA certification and are inclusive of the partial safety factors gf
=1.4 and gm
proportional to each diameter (see ETA).
(3)
Versions Not Certified: white zinc plated and size M6 of stainless steel A4. The recommended loads N, V or F derive from the mean ultimate loads and are inclusive of the total safety factor g=4 (shear g=3).
In the absence of CE markings, the recommended loads derive from tests carried out in the Friulsider laboratory in accordance with the appropriate standards. The load values are only valid if the
installation has been carried out correctly. The designing and calculation of the anchorage should be carried out in accordance with annex C, of the ETAG 001, design method A.
