The Hilti X-BT Fastening System is an innovative method of fastening to pre-painted steel without damaging the surface coating. The system consists of a Hilti powder-actuated tool equipped with specially adapted fastener guides for use with X-BT threaded studs. The X-BT fasteners are stainless steel threaded studs available with thread diameters 8 mm, 1/4" (W6) and 3/8" (W10). The stud, with or without sealing washer, is cleanly set in a small pre-drilled hole in the base steel. The X-BT system is designed to work on carbon steels as thin as 5/16" (8 mm) without through-penetration or damage to surface coatings eliminating time consuming surface preparation and rework (such as with welding).

The X-BT M8 threaded stud, in conjunction with the X-FCM grating disks, can be used to fasten grating to a variety of different steel shapes (Refer to Section 3.4.2.). The W10 and W6 threaded fasteners can be used to support cable/conduit connectors and trays, piping, channels, instrumentation, lighting fixtures, signage, junction boxes, and other fastenings to steel.

Product Features and Benefits

• Efficient:Nothroughpenetrationofbase material — eliminating rework of the base steel coating.

• Fast:100studsperhourcanbeeasily set by one user.

• Durable:Highlycorrosionresistantstainless steel. Fusion to base steel resulting in high load capacities compared to similar methods of fastening.

• Flexible:Worksonmoststeelshapes and thicknesses down to 5/16" (8mm), ideal for both mild and high strength carbon steel base materials.

• Simple:Easytouseportable system requiring no electrical cords or heavy equipment.
