Product Description
TIMCO Velocity 3.5 x 35mm countersunk pozi wood screws (yellow zinc) are a fixing most CCTV and access-control installers keep in the van for mounting brackets, back boxes and containment into timber and chipboard substrates.
Why installers stock these
On a typical camera or panel install, bracket fixing is a small but constant task — internal enclosures, wooden fascia boards, timber-framed partitions and joinery all need a reliable wood screw rather than a masonry fixing. The 3.5 x 35mm size sits in the medium-depth range, suitable where a shorter screw is needed rather than a long structural fixing.
Key specs
- Size: 3.5mm diameter x 35mm length
- Head: countersunk, sits flush with the surface for a clean finish around visible fixing points
- Drive: Pozi recess, reduces cam-out versus standard cross-head drivers when using powered drivers on repetitive fixing runs
- Finish: yellow zinc plated steel for corrosion resistance suitable for interior work
- Materials: timber, chipboard and general wood-based fixing applications
Procurement notes
Countersunk heads matter where a bracket or plate needs to sit flat without proud fixings snagging cabling or trunking. Pozi drive is worth specifying on jobs with high fixing counts, where reduced cam-out saves time and fewer stripped heads mean fewer callbacks. These are general fixing screws for wood-based materials — check substrate type before specifying for masonry or metal applications.
