Installation and handling
| Installation tool | Variable speed electric screw gun |
| Installation drive | Fixfast GreenDrive (8mm hex integral socket with retaining clip) |
| Installation speed | 1500 RPM |
| Correct installation | Fasteners should be driven within three degrees of perpendicular to the surface of the fastened material. Use a depth-setting nosepiece to avoid over-driving, and do not over-tighten. Variants with bonded washers should not have the rubber compressed to less than two-thirds of its uncompressed height. Care should be taken when engaging and disengaging from the fastener head to avoid damage to the protective coating. |
| Handling | Fasteners may have sharp edges, and the use of power tools can be dangerous. Use personal protective equipment. Store fasteners in dry conditions. Inspect each fastener before use and do not use damaged fasteners. |
