Pozi countersunk universal screws with a zinc yellow passivated (ZYP) finish are a reliable general-purpose fixing solution for timber, MDF, chipboard, and similar sheet materials. Available in 3.0mm diameters from 13mm to 25mm, supplied in boxes of 200.
Specifications
| Property | Detail |
|---|---|
| Drive Type | Pozi (Pozidrive) recessed |
| Head Profile | Countersunk |
| Thread Type | Single thread (universal) |
| Finish | Zinc yellow passivated (ZYP) |
| Diameter | 3.0mm |
| Lengths Available | 13mm, 16mm, 20mm, 25mm |
| Pack Size | Box of 200 |
| Lubrication | Wax coated for reduced driving resistance |
What they are used for
- Fixing timber battens, noggins, and studwork in internal carpentry and joinery
- Assembling MDF, chipboard, and plywood sheet materials in furniture and cabinet making
- Securing skirting boards, architraves, and door linings during first and second fix joinery
- General light-duty fixing tasks in dry internal environments where corrosion resistance is a practical advantage
Fitting and handling
These screws are wax lubricated, which reduces friction during driving and makes them well suited to use with a cordless drill or power screwdriver at controlled torque settings. Pre-drilling is recommended in hardwoods or close to the end grain of softwood to prevent splitting. Store in a dry location away from standing moisture to maintain the ZYP coating and keep the wax lubricant effective.
FAQ
What does ZYP mean on screws?
ZYP stands for zinc yellow passivated. The screw is electroplated with zinc and then treated with a yellow chromate passivation layer, which improves corrosion resistance compared to a plain bright zinc finish. ZYP screws are suitable for general internal use but are not rated for external or high-humidity applications.
What is the difference between a universal screw and a wood screw?
A universal screw has a single continuous thread that runs closer to the head than a traditional wood screw, making it suitable for a wider range of materials including MDF, chipboard, and softwood. A traditional wood screw typically has a plain shank section beneath a coarser thread and is more specific to solid timber.
Can I use these screws for external timber fixing?
No. Zinc yellow passivated screws are intended for internal, dry conditions. For external timber such as decking, fencing, or cladding, you should use screws with a stainless steel or hot-dip galvanised finish rated for exterior exposure.
