Product Description
This is a fixing screw, not a CCTV component — but it's a common item for installers mounting brackets, boxes and cabling clips to timber during a camera install.
What it is: a TIMCO Velocity multi-purpose wood screw, 3.5 × 40mm, with a countersunk head so it sits flush once driven in.
Key specs
- Size: 3.5mm diameter × 40mm length
- Head: countersunk, for a flush finish in wood
- Drive: Pozi recess, reduces cam-out with a driver or drill
- Finish: yellow zinc plated steel, for corrosion resistance
- Use: timber, chipboard and general wood fixing
Where it fits on a CCTV job
The 40mm length suits medium-depth fixings — think camera mounting plates, junction boxes or trunking fixed to a wooden fascia, shed frame or stud wall.
Before you buy
Check the timber thickness you're fixing into: 40mm gives reasonable depth without punching through thin battens or fascia boards. If you're screwing into brick, block or render, you'll need a different fixing type — this one is wood-specific.
Pozi drive bits are widely available and match most cordless drivers, so no special tooling is needed beyond a standard Pozi bit.

Frequently Asked Questions
What head type does this screw have?
A countersunk head, so it sits flush with the wood surface once driven in.
What drive does it use?
A Pozi recess drive, which improves grip and reduces cam-out compared with a plain Phillips bit.
Can I use this in masonry for a camera bracket?
No — this screw is designed for timber and chipboard, not brick or block fixings.
Why is the finish yellow zinc?
Yellow zinc plating gives the steel screw corrosion resistance, suited to interior construction and fixing work.
