Product Description
Not a CCTV part — but many installers keep these on the van for mounting timber backing boards, cable trunking battens and equipment enclosures onto wood-based surfaces.
Key specs
- Size: 3.5 x 30mm — diameter x length.
- Head: countersunk, sits flush once driven home.
- Drive: Pozi recess — reduces cam-out versus a plain slot, so the driver bit stays engaged.
- Finish: yellow zinc plated steel — resists corrosion on interior work.
- Material suitability: timber and chipboard, general wood-based fixing.
Where this fits on an install
A flush countersunk head matters when a mounting plate or bracket needs to sit tight against a timber backing board — a proud screw head will stop hardware seating properly. The Pozi drive suits repetitive fixing runs, where consistent bit engagement saves time over a full day's install.
What to check before ordering
These are wood screws, not rated for masonry or metal fixings. Confirm your backing material is timber, chipboard or similar wood-based board before specifying this screw for the job.
