TIMCO Velocity Wood Screws 3.5x50mm Countersunk Pozi Yellow Zinc

This isn't CCTV kit — it's a fixing you'll likely reach for when mounting brackets, boxes or timber battens as part of a camera install, which is why we stock it alongside our security gear.

The Velocity 3.5x50mm Wood Screws Countersunk Pozi Yellow Zinc are a general-purpose screw for timber, chipboard and similar wood-based materials. The 3.5mm diameter and 50mm length suit medium-duty fixing jobs — think securing a mounting plate to a timber fascia or joining wood components where a longer screw is needed to bite properly.

Why the design matters

• Countersunk head — sits flush with the surface once driven home, so brackets or fittings seat properly against it.
• Pozi drive recess — gives the driver bit better grip in the screw head, cutting down on cam-out (the bit slipping out under torque) so you can apply more force without stripping the recess.
• Yellow zinc plated steel — the plating resists corrosion for internal building applications, which matters if the screw is fixing something inside a loft, cupboard or wall cavity.

They're aimed at timber and engineered wood — chipboard, MDF-type boards and similar — rather than masonry or metal fixing. If you're mounting a camera bracket to a solid wood or timber-framed surface, this is the kind of screw that does that job; for brick or block you'd need a different fixing entirely.
