Product Description
Key specs
- Size: 3.5 × 45mm (diameter × length)
- Head: countersunk, for flush fitting
- Drive: Pozi recess
- Finish: yellow zinc plated steel
- Substrates: timber, chipboard and general fixing applications
Fixing brackets, back-boxes, junction boxes and enclosures to timber-based surfaces is a routine part of CCTV first-fix work — battens, joists, fascias and chipboard backing panels all need a screw that seats flush and drives cleanly on site.
Why the spec matters on install
The countersunk head sits flush once driven home, so bracket plates and enclosure lugs pull down tight against the timber without the head standing proud. The Pozi recess is designed to improve driver engagement over a plain slot, which counts when a fixing is being driven one-handed at height or in a loft void with limited access.
The yellow zinc plated steel finish gives the screw corrosion resistance, suited to interior construction and installation work. At 45mm this is the slightly shorter alternative to the 50mm TIMCO Velocity screw, so check reach against the substrate thickness before specifying for a given job.
Velocity 3.5x45mm Countersunk Pozi Wood Screws Yellow Zinc are TIMCO Velocity multi-purpose wood screws for timber, chipboard and general fixing.
