Designed for reliable performance in wood-based applications, the Solo Chipboard & Woodscrews PZ Double Countersunk Yellow 4.5mm offer excellent grip and drive efficiency. Their sharp, single-thread design allows fast penetration and high pull-out resistance, especially in chipboard, MDF, and softwoods. The double countersunk head enhances head strength while allowing a neat flush finish, reducing the risk of surface splitting. With a yellow zinc passivated coating, they also provide corrosion resistance for indoor use. Ideal for general wood joinery and furniture assembly where consistent holding power is essential.
