MT angles ( MT-10 and MT-15 ) are ultra-light profiles that are used primarily for light-duty trapeze applications . In such applications , MT angles are installed in a horizontal orientation and supported vertically by threaded rods with nuts . Note : MT connectors are not intended for use with angle profiles . |
Open channels ( MT-20 , MT-30 , MT-50 , and MT-60 ) may be used for a wide range of light-duty to mediumduty applications . Channels can be used as beams or columns . While these members can resist bending , shear , and compression , they are not recommended for use with torsional loading . MT open channels have full 2D and 3D connectivity capabilities with MT connectors . |
Closed MT profiles ( MT-70 , MT-80 , MT-90 , and MT-100 ), or “ girders ”, are used for heavy-duty applications . The closed shape of these profiles results in a greater cross-sectional area compared to similarly sized channels and , accordingly , yields significantly higher capacities in bending , shear , compression , and torsion . Reinforced holes along each girder face provide greater contact area for thread forming with the MT Thread Forming Bolt ( MT-TFB ) connection mechanism . |
MT brackets of various sizes and lengths act as cantilevered beams . With 2-hole and 4-hole base plate options , MT brackets can anchor to concrete , attach to MT channels and girders , or directly fasten to steel . |
The twist-lock mechanism ( MT- TL with MT-TLB ) may be installed anywhere along the open face of MT channels . Once installed , a high shear capacity is then made possible by the innovative twist-lock ( MT-TL ) and its “ On-The-Spot ” serration . Hilti MT-TFB Thread Forming Bolts securely connect to closed profiles ( girders ) without the need for nuts or additional washers , as the washer is integrated within the head of the MT-TFB . During installation , a robust thread is formed within the reinforced girder hole , minimizing the risk of thread stripping . |
Many of the connectors in the MT portfolio may be used as either base connectors or as system connectors ( to MT channels or girders via MT-TFB ). Using bolt holes in the MT channels and girders that interlock with the clouded and slotted holes in the connectors , MT systems are adjustable up to 1 " on the first installation , and can be fine adjusted by 3 / 16 ". |
Connections to steel are made using robust beam clamps and innovative direct fastening technology ( X-BT / S-BT / F-BT ). The base plates are designed to cover a large range of standard steel profiles with flange widths up to 12 ". Girder clamping accommodates steel profiles with flange widths greater than 12 ". |
MT connector base plates can be anchored to concrete using a variety of Hilti anchors . Choose from mechanical and chemical anchors according to loading and base material conditions . |

MT channel connectors , when used in combination with the twistlock mechanism , act as system connectors between channel profiles . Many of these connectors can be installed in a variety of configurations . |
