TIMCO Velocity Wood Screws 3.5x20mm Countersunk Pozi Yellow Zinc

TIMCO's Velocity 3.5 × 20mm countersunk screw is a fixing for CCTV installers to keep alongside cable and brackets, not a headline product — but it's one that shows up on every job sheet. It's a small-gauge wood screw suited to mounting brackets, junction boxes and light timber fixings where deep penetration isn't needed.

Where it fits on a CCTV job

Installers use screws in this class for fixing camera brackets to timber fascias, securing cable clips and battens, and mounting smaller enclosures to wooden surfaces. The 20mm length suits shallow fixing depth — think fascia boards, softwood battens or thin panelling — rather than structural fixing into masonry or deep timber sections.

Key specs

• Size: 3.5mm diameter × 20mm length
• Head: countersunk, sits flush for a clean surface finish
• Drive: Pozi recess, reduces cam-out for controlled driving by hand or power tool
• Finish: yellow zinc plated steel, corrosion resistant
• Material use: timber, chipboard and general wood-based fixing

Selection notes for buyers

Choose this length when the fixing depth is shallow — mounting a bracket to a thin board or batten rather than through into a deep structural timber. For heavier camera housings or thicker mounting surfaces, a longer or larger-diameter Velocity screw from the same range will give more secure engagement. Keep a mixed stock of lengths on the van rather than ordering length-by-length per job.
