Zenith Screw Treated Pine TC SQ 8-10 x 25mm 100 Pk

If you're working with treated pine outdoors — fencing, landscaping, decking framing, retaining structures — standard galvanised screws are the wrong choice. The chemical preservatives used in treated pine are corrosive to standard zinc and galvanised coatings, causing premature degradation and staining that shortens the life of both the fastener and the timber. The Zenith Tufcote Treated Pine Screw is engineered specifically for this environment, with a Tufcote coating designed to outperform galvanised finishes in contact with treated timber preservatives.

At 8G x 25mm, it's the compact size in the Tufcote range — ideal for thinner treated pine members such as battens, trims, and light cladding where a shorter fixing is all that's needed. The coarse thread bites firmly into softwood for maximum grip, the ribbed countersunk head pulls cleanly flush, and the square (Robertson) drive provides significantly more resistance to cam-out at higher torque than Phillips — a real advantage when running a full fencing job. Made from C1022 hardened carbon steel. Supplied in a 100-pack.
