| 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. |

                        Description
                    Carbon steel high thread fastener for fixing composite panels to heavy steel.
Features & Benefits
                    - High thread provides optimal clamping force to top sheet
- Superior quality carbon steel
- Consistently high pull-out and shear values
- Unique Enduroguard coating for excellent corrosion resistance
- Supplied pre-assembled with an Aluminium / EPDM rubber 29mm diameter sealing washer, normally used for fastening rooflights. Hexagon head rooflight fasteners should always be capped with a red colour cap
Application
                    - For mechanically fixing composite panel systems to heavy steel purlins and sections

                    | Installation tool | Variable speed electric screw gun | 
| Installation drive | Fixfast YellowDrive socket | 
| 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. |
