Countersunk Zinc Yellow Passivated Wood Screw 4.5 x 80mm

Summary

A 4.5 x 80mm countersunk wood screw with a zinc yellow passivated (ZYP) finish, suitable for general timber fixing and joinery applications. The corrosion-resistant coating makes it appropriate for use in treated timber and moderately demanding environments. Ideal for trade joiners, carpenters, and site fixers requiring a reliable, medium-to-large format wood screw.

Features

• Countersunk head profile allows the screw to sit flush with or below the timber surface for a neat finish.
• Zinc yellow passivated finish provides enhanced corrosion resistance compared to standard bright zinc plated screws.
• 4.5mm diameter offers excellent holding power in both softwood and hardwood substrates.
• 80mm length makes it well suited to fixing thicker timber sections, structural joinery, and framing applications.
• Thread form optimised for wood, providing strong pull-out resistance and reduced splitting.
• Compatible with standard Phillips (PZ2) or Pozi drive bits for fast, controlled installation.
