Hilti HIT-HY 200

Hilti HIT-HY 200 is the medium-load companion specification to HIT-RE 500 V4 in TRSC's anchor and reinforcement library. The product earns its specification slot for three reasons: faster cure time (typically 50% faster than HIT-RE 500 V4 at the same temperature), broader low-temperature operating range (approved for installation down to -10°C, vs. +5°C for HIT-RE 500 V4), and lower unit cost per installation, which matters at production volume on large commercial fit-outs. The product is selected on three job profiles: (1) production anchoring on commercial fit-out (services penetrations, balustrade fixing, mechanical equipment supports) where unit cost and cycle time control the engineering economics; (2) post-installed reinforcement on light to medium retrofits where the embedment depth and load case are within the HIT-HY 200 approval envelope (typically up to 20 d_b for post-installed rebar, vs. up to 60 d_b for HIT-RE 500 V4); (3) steel-frame baseplate fixing on industrial and commercial buildings where the anchor design is governed by mechanical capacity rather than seismic or deep-embedment criteria. The most common specification pitfalls TRSC encounters in the field are: (1) wrong product selection for the load case — field crews routinely substitute HIT-HY 200 for HIT-RE 500 V4 on the basis of installer convenience, even where the engineering design specifies the deep-embedment epoxy product; the substitution invalidates the design and the contractor must be told explicitly that the products are not interchangeable; (2) hole cleaning — HIT-HY 200 manufacturer instructions for use require the same 4-step or 6-step hole-cleaning regime as HIT-RE 500 V4 (blow-brush-blow-brush-blow-brush, compressed air at minimum 6 bar, Hilti HIT-RB brush sized to hole); the perception that hybrid mortars are less sensitive to substrate cleanliness is incorrect and is a common cause of pull-out failures; (3) seismic approval level — HIT-HY 200 holds C1 seismic approval but not the C2 approval that HIT-RE 500 V4 carries; for seismic-controlled installations in NSW and VIC, the engineer must confirm the seismic approval level required by the design. TRSC anchor specifications include the product nomination, the embedment depth, the seismic approval level, the hole-cleaning regime, and a witness hold point at the start of the first installation.
