Product Description
3.5 × 25mm yellow zinc-plated wood screw from TIMCO's Velocity range, countersunk with Pozi drive.
Key specs
- Diameter × length: 3.5 × 25mm
- Head: Countersunk, for flush finish
- Drive: Pozi recess
- Finish: Yellow zinc plated steel
- Substrates: Timber, chipboard and general wood-based fixings
Application notes
The countersunk head seats flush once driven home — relevant where a proud head would foul a fitted panel or enclosure lid. Pozi recess reduces cam-out versus a plain slot, which matters when driving a batch with a powered screwdriver rather than by hand.
Yellow zinc plating gives corrosion resistance suited to interior work. Thread is cut for grip in timber fibre; at 25mm length, penetration is shallow, so this size suits thin board or where the receiving timber depth is limited rather than deep structural fixings.
Use case
On install jobs this size sees use for fixing junction boxes, cable clips, brackets or light fittings to timber battens, joists or chipboard backing where a shallow, flush fixing is needed — general carpentry and joinery duty rather than heavy load-bearing work.
No load ratings, packaging quantities or coating spec (e.g. salt-spray hours) are stated by the manufacturer for this listing — confirm against TIMCO's own datasheet if the application is load-critical.
