Before you start
Check that your drill or impact driver has compatible bit holders or sockets for the included impact driver bits. Inspect the site case on delivery to ensure it has not been damaged in transit, as the case protects your fixings on site. Ensure you have the correct screw size and length for your application before installation, referring to the case labelling. The smaller gauges (4mm and 4.5mm) are suitable for lighter work and fine joinery, whilst the 5mm gauge screws are better for heavier construction applications.
- Verify your tools are compatible with the included bits
- Check the site case for damage on delivery
- Select the correct screw size for your specific application
- Use smaller gauges (4-4.5mm) for fine work and joinery
- Use larger gauge (5mm) screws for heavier construction
