Recommended loads (predominantly static)
Fastening wood to concrete, sandlimemasonry
or to steel
Design conditions:
• For safety relevant fastenings sufficient redundancy of the entire system is required:
Minimum 5 fastenings per fastened unit with normal weight concrete base material.
• Valid for 27 mm embedment depth.
• Increase to 600 N possible if 8 or more fastenings in each fastened unit.
• All visible failures must be replaced.
• Valid for concrete and sand lime-masonry with strength of fcc < 30 N/mm2 Nrec = Vrec = 600 N

.
• Fastened material: wood, minimum thickness = 24 mm
plywood, minimum thickness = 16 mm
Soft material:
• Working loads depend on strength and thickness of material fastened. Do not use working
loads in excess of those for wood.
• Use R23 or R36 (∅4.5 mm hole) washer to control penetration and to increase pullover
strength. Separately available from Hilti.
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.
