- Head: countersunk, sits flush with the material surface
- Drive: Pozi recess, for improved driver engagement and reduced cam-out
- Finish: yellow zinc plated steel, for corrosion resistance
- Material suitability: timber, chipboard and general wood-based fixing
Application
This is a general-purpose wood screw, not a fixing rated for masonry or metal. Use it for timber, chipboard and other wood-based materials in carpentry, joinery and DIY work.
The countersunk head lets the screw seat flush once driven, which matters where a proud head would interfere with a mounting plate, bracket or enclosure — relevant on installation jobs where cable management panels or timber backing boards need a clean surface.
The Pozi recess is intended to reduce cam-out compared with a plain slot, giving more consistent engagement with driver bits during repetitive fixing runs.
Length considerations
At 30mm, this screw suits lighter-duty timber fixings — thin boards, small fittings, backing panels — rather than jobs needing deep penetration into thicker timber sections. Where more holding depth is required, a longer screw from the range would be the better choice.
Finish
Yellow zinc plating gives the steel body corrosion resistance suited to interior building work and general installation tasks.
