3.2.7 X-R FASTENERS FOR FASTENING TO STEEL
3.2.7.1 PRODUCT DESCRIPTION
The Hilti X-R powder-actuated fasteners are manufactured from a proprietary CrMnMo alloy which has corrosion resistance for outdoor environments in mildly corrosive conditions where HDG coated parts are commonly specified or used . The proprietary alloy provides a high hardness level , increasing the application limit when compared with traditional alloys . See Material Specification and Application Limit sections with more information .
