Hilti powder-actuated fastening systems have been designed
and produced to develop reliable performance. Factors that
influence pullout strength have been identified through an
understanding of the anchoring mechanisms, technical expertise and testing.
Some of these factors are:
• Depth of penetration in the base steel
• Surface and material characteristics of the fastener
• Coating on the steel base material
• Driving velocity/energy
• Diameter and geometry of the fastener shank
