3.2.16 STANDOFF ADAPTERS FOR THREADED STUDS
3.2.16.1 PRODUCT DESCRIPTION
The MR and MF standoff adaptors are used in conjunction with Hilti X-BT and S-BT threaded stud fastening systems , to provide an extension to those fasteners . The threaded studs are installed into steel , according to their installation instructions , to provide a threaded protrusion for a variety of applications , including fastening of electrical cables and conduit , support of slotted framing channel ( strut ) and hanging of pipes from steel . Both the X-BT and S-BT systems provide a high level of corrosion protection for the steel that is being fastened to . Please see Sections 3.2.14 and 3.2.15 for detailed information regarding these products .
The Standoff Adapters are supplied in four lengths , in order to accommodate situations where a cantilever is needed to complete the application . Specifically , the adapters are used when fastening directly to steel with thick coatings , such as intumescent fire protection coatings . A small cylindrical section of the coating is removed using a special tool , allowing for installation of the X-BT or S-BT stud , followed by screwing the adaptor on the installed threaded stud . The adapter allows for various elements to be attached without damage to the coating as may occur with traditional methods like welding or clamping .
