Test data
Important note: Test data are for information only and can't be used for design. These data
are examples and not representing the whole range of applications and load cases. For more
detailed information please contact Hilti.
X-FCM-R mean ultimate Nu,m and characteristic Ntest tensile loads:
Notes/Conditions:
• Except for loads noted with*, recommended tensile
loads are limited by elastic limit of disk.
• Exceeding recommended loads can result in plastic
deformation of disk.
• X-FCM, X-FCM-M, X-FCM-R resist shear by friction
and are not suitable for explicit shear load designs,
e.g. diaphragms. Depending on surface characteristics,
shear loads of up to about 0.3 kN will not result
in permanent deformation. Therefore, small unexpected
shear loads can generally be accommodated
without damage.
