Failure to adequately clean your holes can significantly reduce the performance of conventional adhesive anchor systems. This is why Engineers at Hilti have created new Safe Set™ Technology which eliminates manual hole-cleaning during anchor installations.
For holes that clean themselves, we recommend the new Hilti TE-CD and TE-YD Hollow Drill Bits in conjunction with the Hilti VC 20/40 vacuum to create a virtually dustless working environment. Contractors using this new system in conjunction with Hilti HIT-HY 200 adhesive enjoy higher productivity, fewer cleaning errors, and more precise installations.
The new Hilti HIT-Z cleaning rod features a cone shaped helix that works as a torque-controlled anchor. Thanks to their shape, HIT-Z Anchor Rods, can be installed in a standard (hammer drilled, dry or water saturated concrete, above 41°F/5°C) uncleaned hole. Again, HIT-Z Anchor rods are designed for use with Hilti HIT-HY 200 adhesive.
The most common anchor installation method uses compressed air and a wire brush (also known as traditional brush and blow) to clean drill holes. Like all Hilti adhesive anchors, HIT-HY 200 can be easily utilized using this method because the adhesive only requires two blows of compressed air, two brushes and two more blows of compressed air (2x2x2). Applying HIT-HY 200 with brush and blow is more efficient than using competitive adhesives which typically require at least a 4x4x4.
Hilti HIT-HY 200 is available in two versions with the same load ratings: HIT-HY 200-R for “regular” working times and HIT-HY 200-A for applications requiring “accelerated” working times. The Hilti HIT-HY 200 Adhesive Anchor System installed with the Hollow drill bit method, HIT-Z or standard hole cleaning method is approved by ICC-ES in the ESR 3187 for use in all seismic zones and uncracked and cracked concrete.
Please note: Hilti HIT-HY 200 Adhesive replaces both HIT-HY 150 MAX and HIT-HY 150 MAX-SD Adhesive as these products will be discontinued.
