Product Description
These are TIMCO Velocity 3.5 × 30 mm countersunk Pozi wood screws, a fixing most installers will already have on the van for the small jobs that surround a bigger job.
On a CCTV or access-control install, the camera bracket, junction box or cable clips rarely need the heavy fixings — this is the size that does the actual box-lid, batten or trim fixing once the main hardware is up. The 30 mm length suits lighter-duty timber fixings where you don't want deep penetration, such as fixing thinner boards, trims or fittings rather than structural timber.
Key specs
- Size: 3.5 mm diameter × 30 mm length
- Head: countersunk, sits flush with the surface
- Drive: Pozi recess that limits cam-out when using a driver or drill
- Finish: yellow zinc plated steel, for corrosion resistance in interior work
- Designed for timber, chipboard and general wood-based fixings.
Where these fit on site
Builders, carpenters and general installers use this size for fixing timber boards, assembling furniture, mounting fittings and general wood construction tasks — useful as a standing stock item alongside cable, brackets and enclosures rather than a one-job buy.
Keep in mind the yellow zinc finish is described as suited to interior building work rather than exposed exterior fixing.
