Product Description
TIMCO Velocity 3.5x45mm Wood Screws Countersunk Pozi Yellow Zinc are a general-purpose fixing for timber and chipboard, useful wherever you're mounting brackets, back-boxes, junction boxes or enclosures during a CCTV install.
What they do
The countersunk head sits flush once driven home, so a bracket plate or enclosure lug pulls down tight against the timber rather than sitting proud. The Pozi drive recess is designed for better driver engagement than a plain slot — handy when fixing one-handed at height or in a loft void with limited access.
Finish and where to use them
These screws are yellow zinc plated steel, giving corrosion resistance for interior construction and installation work. For exterior fascias, soffits or any fixing exposed to the weather, check with your installer or the manufacturer's datasheet for a finish rated for outdoor exposure.
Where they fit
Beyond CCTV first-fix work, these are general carpentry, joinery and DIY screws — suited to assembling wooden components, fixing boards and installing fittings in timber, chipboard and other construction materials.

Frequently Asked Questions
Can I use these for fixing a CCTV camera bracket to a timber fascia outdoors?
The yellow zinc finish suits interior construction and installation work, so for an exterior fascia exposed to weather, check with your installer or the manufacturer's datasheet for an outdoor-rated screw.
Will the Pozi drive help when fixing at height or in a loft void?
Yes — the Pozi recess is designed to give better driver engagement than a plain slot, which helps when driving one-handed with limited access.
Are these screws only for CCTV installs?
No — they are general-purpose screws for carpentry, joinery, construction and DIY, suited to timber, chipboard and other construction materials, with CCTV fixing being just one use.
Is the 45mm length the only size available?
No. 45mm is a medium-depth option, slightly shorter than the 50mm version, for jobs that don't need the longer screw.
