Timco 4.0x40mm Double Countersunk Stainless Steel Screws - Pack of 15

The Timco Classic Multi-Purpose Screws are manufactured from high-quality A2 Stainless Steel, offering superior corrosion resistance—ideal for use in humid or corrosive environments or with inherently corrosive materials like Green Oak. These screws are surface-hardened up to 750 HV to prevent torque shearing under load while maintaining a core hardness of 450 HV for optimal ductility.

Key Features:

• Double countersunk head – Minimises head shear risk and ensures a flush finish.
• 40° deep single thread – Enhances pull-out resistance for secure fastening.
• Single slash on 25mm+ lengths – Reduces torque and timber splitting when screwing near edges.
• Fully threaded up to 75mm (thread length: 35mm for 40mm screws) – Ensures strong grip in all materials.

Applications:

• Softwood & hardwood (pre-drilled)
• Chipboard & MDF
• Plastic & corrosion-prone materials

These screws are Pozi-drive (PZ2) compatible, featuring a sharp 25° point for easy penetration.
