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.
Design data for Hilti standard nails in concrete are based on a specific statistical evaluation
method taken into consideration high variation coefficients. The evaluation procedure is
described within section Direct Fastening Technology of this manual. For more detailed
information please contact Hilti.
