Timco Classic Multi-Purpose Screws, PZ Double Countersunk, 4.0 x 70mm (200 pcs)

The Timco Classic Multi-Purpose Screws are engineered for versatility across various materials including hardwood, chipboard, MDF, plastic, and thin sheet metal. Their 25° sharp point, combined with a special thread design and corrosion-resistant plating, ensures efficient and consistent performance with exceptional holding power.

• Double countersunk head minimises the risk of head shear and facilitates easier countersinking.
• Patented lubrication accelerates insertion time while enhancing corrosion resistance.
• 40° deep single thread provides a secure fixing with excellent pull-out resistance.
• Surface-hardened (750 HV) prevents torque shearing under heavy loads, while the core hardness (450 HV) maintains ductility.
• 25mm+ single slash design reduces torque and prevents timber splitting when inserted near edges.

These screws are fully threaded up to 75mm, while lengths of 80mm and above feature a 70mm threaded portion for optimal grip and strength.
