Description
Self-tapping stitcher fastener with a hex head. Pre-assembled with a 16mm stainless steel washer. Often used to replace fasteners that have been removed.
Features & Benefits
- Manufactured from 100% A2/304 stainless steel
- 8.0mm diameter, fully threaded fastener to ensure effective clamping
- Nail point for accurate location into a pre-drilled hole
- Supplied pre-assembled with a stainless steel / EPDM rubber 16mm diameter sealing washer, normally used in wall applications
Application
- For mechanically fixing multiple layers together including sealants
- Fasteners are intended as a repair screw, to be installed into locations previously vacated by other ‘stitchers’
- Suitable for tapping into a maximum of 2 x 1.2mm steel or 2 x 1.5mm aluminium

| NR,II,K (Tensile - Pull-out) | Steel 0.465mm S280: 0.75 kN |
| Steel 0.5mm S250: 0.75 kN | |
| Steel 0.7mm S220: 1.09 kN | |
| Steel 0.7mm S280: 1.21 kN | |
| Steel 0.9mm S280: 1.63 kN | |
| Aluminium 1.2mm 3004: 1.51 kN | |
| Aluminium 1.5mm 3004: 2.27 kN |
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. Impact drivers should NOT be used when installing these fasteners. EPDM sealing washers are required where air and water sealing is necessary. 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. |
