Galvanised Round Wire Nails 65 x 2.65mm 2.5kg are a common type of nail used for a multitude of construction, carpentry, and general building applications, particularly where medium-level corrosion resistance is needed. The nails are manufactured from carbon steel and feature a full round head for secure clamping and a smooth shank.1 The galvanised finish means they are coated with a layer of zinc to provide protection against rust, making them suitable for use in both internal and covered external applications (often classified under Service Class 2).2 The specifications indicate a nail length of 65mm (approximately 3$2 \frac{1}{2}$ inches) and a diameter or gauge of 2.65mm.4 Common applications include roofing battens, fencing, framing, decking, and general timber fixing.5 A 2.5kg pack of this size typically contains an approximate count of 875 nails (based on 350 nails per 1kg).
