Timco Double Countersunk Multi-Purpose Screws, PZ, Yellow, 4.5x55mm (200 Pack)

Timco Classic Multi-Purpose Screws are precision-engineered fasteners designed for exceptional performance across a variety of materials including hardwood, chipboard, MDF, plastic, and thin sheet metal. With their sharp 25° point and special thread design, these screws ensure quick, efficient insertion and excellent holding power. The patented lubrication not only enhances insertion speed but also provides superior corrosion resistance, making them ideal for both indoor and outdoor applications.

The 40° deep single thread ensures a secure fixing with high pull-out resistance, while the surface-hardened design (up to 750 HV) prevents torque shearing under heavy loads. A core hardness of up to 450 HV improves ductility, ensuring the screws remain durable and reliable. Additionally, the single slash on 25mm+ lengths reduces torque and minimises the risk of timber splitting, particularly when inserted near edges.

Each pack contains 200 screws, all featuring a double countersunk head to reduce head shear and assist in countersinking. With a Pozi recess (PZ2 bit size) and zinc & yellow finish, these screws combine functionality with high visibility for easy identification and use.
