Hilti offers a variety of solutions to various corrosive environments that help reduce or eliminate the drawbacks of traditional methods. Depending on the corrosive environment and type and thickness of the base material, Hilti offers three different fastening options. These solutions help maintain the corrosion resistance of the structural steel and the connection to the non-structural components.
From traditional methods for fastening to steel
1) Welding
Time consuming preparation of the coated steel e.g. with an angle grinder
Creates a lot of sparks, which can be a hazard
2) Through bolting
Drilling process can be time-consuming depending on the thickness and hardness of the steel
Steel exposed from the drilling must be properly coated to avoid corrosion
3) Clamping
Limited in direction of attachment of the component since clamps require a specific orientation relative to the structural steel
Very high material costs, especially for corrosion-resistant clamps in hot-dip galvanized or stainless steel
Eliminates the need for base material preparation and re-work

Eliminates the need for base material preparation and re-work
Unlike welding or through bolting, Hilti fastening solutions do not require preparation of base material and re-work after the fastening is made. This makes the overall installation much faster, while providing reliable corrosion protection.
Skilled welder is not required

Hilti blunt tip fastening on steel can be completed by any trained operator and do not require a certified welder. Therefore, contractors can deploy welders to other critical applications where welding is an absolute must.
Only access to one side of the steel is needed

Only access to one side of the steel is needed
Unlike through bolting or clamping, Hilti fastening solutions do not require access to both sides of the steel. This further improves operator safety as there is no need to get fingers into tight spaces.
Weather independent and no external power source required

Hilti sharp tip solutions are for powder-actuated nailers, so can be used under all weather conditions. Cordless drills used for blunt tip solutions are built for tough jobsite conditions, so can be used in nearly all weathers. In addition, the cordless tools are powered by 22V Li-ion batteries so do not require a mains power supply.
Backed by testing and approval

Hilti provides comprehensive technical data for different thicknesses and strengths of base steel. This data is backed by International Codes Council’s Evaluation Service (ICC-ES) as well as industry approvals including, but not limited to, the American Bureau of Shipping (ABS). In addition, Hilti blunt tip screw fastening technology has been tested, and is approved for use, in aluminum base material.
Easy to check installation quality
