Galvanised Round Wire Nails 75 x 3.75mm 2.5kg are heavy-duty fasteners perfect for larger timber construction and exterior projects. The nail's dimensions are 75mm in length (approximately 3 inches) and 3.75mm in diameter (gauge), providing substantial depth penetration and a thick shank for strong holding power and resistance to bending. They feature a full round head to ensure a secure, flush finish and are zinc-coated to be corrosion-resistant, making them ideal for applications like fencing, roofing battens, timber framing, and general outdoor carpentry where exposure to weather is a factor. This 2.5kg pack is a large, trade-size quantity that typically contains an approximate count of 385 nails (based on approximately 154 nails per 1kg).
