TIMCO Velocity Wood Screws 3.5x25mm Countersunk Pozi Yellow Zinc

TIMCO Velocity Wood Screws 3.5x25mm Countersunk Pozi Yellow Zinc are multi-purpose fixings for timber and chipboard, sized 3.5mm diameter by 25mm length.

Key specs

• Diameter × length: 3.5 × 25mm
• Head: Once driven in, the countersunk head ends up level with the surface.
• Drive: Pozi recess — matches a Pozi bit for better engagement than a plain slot
• Finish: Yellow zinc plated steel — corrosion resistance for interior use
• Substrates: Timber, chipboard and general wood-based fixing

What this means on the job

A countersunk head means no proud screw head sitting above the surface — useful where a flat, flush finish matters, such as furniture panels or trim. The Pozi drive needs a matching Pozi driver bit or screwdriver tip; using the wrong bit type increases the chance of slipping.

At 25mm long, penetration into the receiving material is shallow. This length suits thinner boards or fixings where the timber depth behind the surface is limited, rather than deep structural joints needing longer screws.

The yellow zinc plating protects the steel from corrosion in normal interior conditions. TIMCO Velocity screws in this size are aimed at carpentry, joinery and general DIY fixing tasks rather than heavy structural work.
