This pack of 500 Diall olive coated shallow countersunk screws is designed for builders and DIY enthusiasts working on decking or general construction projects. The key benefit is their durable carbon steel construction and olive coating for enhanced longevity and subtle aesthetics. A potential consideration is their partially threaded design, which may influence holding power in certain applications. These screws feature a 60mm length, 5mm diameter, and are partially threaded for 58mm, with a PZ drive for secure fastening.

These screws are primarily designed for decking and general multipurpose use in construction, offering durability and a discreet finish.
No, these screws are partially threaded for 58mm of their 60mm length. This design is often beneficial for holding power in decking applications.
You will need a PZ (Pozidriv) screwdriver or bit for these screws, as indicated by the PZ drive type.
Yes, they can be used for interior projects, but their olive coating and partial threading are particularly suited for outdoor applications where corrosion resistance is important.
This pack contains 500 screws.
The screws are 60mm in length and have a 5mm diameter.
Ensure you are using the correct PZ driver bit and that the pilot hole is appropriately sized. For harder woods, a slightly larger pilot hole may be necessary, or the countersink needs to be initiated before full insertion.
Check if the material is too soft or if the pilot hole is too large. For softwoods, a fully threaded screw might offer better grip. Ensure the screw has entered solid material.
Verify you are using a PZ driver and not a Phillips head. Ensure your screwdriver or drill has sufficient torque. Pre-drilling a pilot hole, especially in dense wood, will ease insertion.
While coated, prolonged exposure to moisture can lead to rust. Store screws in a dry place. For existing rust on installed screws, consider applying a protective sealant or replacing the screw if rust is severe.
Setup:
These screws require a PZ (Pozidriv) screwdriver or drill bit for proper insertion. Ensure the screw head is fully countersunk for the best aesthetic and functional outcome. Pre-drilling pilot holes, especially in hardwood, can prevent wood splitting and ease insertion. The pilot hole diameter should be slightly smaller than the screw's core diameter.
Compatibility:
Compatible with standard PZ drive screwdrivers and power tools. Suitable for use with most common softwood and hardwood timber applications, as well as other construction materials where appropriate.
Care:
While the olive coating offers good corrosion resistance, it is advisable to store screws in a dry environment to prevent premature rust or degradation. Periodically inspect outdoor constructions for signs of wear or corrosion on the screws, especially in highly exposed or coastal environments.
