How and where to use guide
ULTIMATE SITE CASE ZYP
Typical applications
This assortment is suitable for general carpentry, joinery, timber frame assembly, and construction work where multiple screw sizes are required. The pozisquare head design works with both Phillips and Pozidriv drivers, offering flexibility on site. The zinc and yellow plated finish provides corrosion resistance suitable for interior and protected external applications. Use the larger screws (5mm diameter in 70mm, 80mm, and 100mm lengths) for structural timber connections and fixing heavy components. The medium sizes (4mm and 4.5mm) are ideal for general framing, carcassing, and standard joinery work. The smaller gauges (4mm and 4.5mm in 30mm to 50mm lengths) suit fixing trim, battens, and lighter components.

- Fixing battens, trim, and cladding
- Interior and protected external applications
- Mixed-size projects where multiple gauges are needed
On-site usage and storage
The robust site case is designed for outdoor and on-site conditions, protecting the screw assortment from weather and site damage. Store the case in a dry location to prevent corrosion of the zinc plated finish. The included impact driver bits allow immediate use with cordless impact drivers, though the pozisquare head also accepts standard Phillips and Pozidriv bits for manual or conventional power driver use. Keep the case organised by size to avoid delays when selecting the correct fastener for each task.

Limitations and finishing
The zinc and yellow plated finish is suitable for interior use and protected external applications, but is not recommended for exposed coastal environments or areas subject to severe corrosion risk. For such applications, consider alternative finishes. The double countersunk head design provides a neat finish flush with the timber surface, but requires correct countersinking to avoid surface damage. Always use the correct gauge and length for your application to ensure adequate holding power and avoid splitting timber or over-tightening.
