X-BT Fastening Systems 3.2.10 3.2.10.1 Product Description The Hilti X-BT Fastening System is an innovative method of fastening to prepainted 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 predrilled 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: No through penetration of base material eliminating rework of the base steel coating. Fast: 100 studs per hour can be easily set by one user. Durable: Highly corrosion resistant stainless steel. Fusion to base steel resulting in high load capacities compared to similar methods of fastening. Flexible: Works on most steel shapes and thicknesses down to 5/16" (8mm), ideal for both mild and high strength carbon steel base materials. Simple: Easy to use portable system requiring no electrical cords or heavy equipment. 3.2.10.1 Product Description 3.2.10.2 Material Specifications 3.2.10.3 Technical Data 3.2.10.4 Installation Instructions 3.2.10.5 Information X-BT W6, X-BT W10, X-BT M8 Listings/Approvals ICC-ES (International Code Council) ESR-2347 COLA (City of Los Angeles) RR 25684 UL (Underwriters Laboratories) X-BT W10 and X-BTW6 with sealing washers for use as Grounding Studs Note: UL listing does not include X-BT M8 or any X-BT studs without sealing washers ABS (American Bureau of Shipping) Lloyds Register GL (Germanischer Lloyd) DNV BV (Bureau Veritas) 3.2.10.2 Material Specifications Part Shank Threaded Sleeve Washer Sealing Washer Material High Corrosion Resistant Stainless Steel X2CrNiMo 17132 X5CrNiMo 17-12-2+2H Elastomer, black resistant to: UV, salt water, water, ozone, oils, etc. Tensile Strength, F u ksi (N/mm 2 ) 205 (1400) 110 (750) 110 (750) N/A X-BT W6-24-6 1.232" [31.3] 0.945" [24] 0.472" UNC 3/8" ø 0.177" [4.5] [ø 12] X-BT W10-24-6 0.839" [21.3] 0.551" [14] 0.472" M8 [ø 12] X-BT M8-15-6 ø 0.177" [4.5] 1 and sealing washer only found on X-BT M8-15-6, X-BT W6-24-6 and X-BT W10-24-6.
