Timco Classic A4 Stainless Steel Screws 3.5x20mm, 200pc, PZ Double Countersunk

Timco Classic Multi-Purpose Screws offer superior performance with marine-grade A4 stainless steel construction, making them ideal for use in coastal and highly corrosive environments. These screws are perfect for fixing to softwoods, hardwoods (when pre-drilled), chipboard, MDF, and plastic.

The double countersunk head reduces the likelihood of head shear and ensures a flush finish, while the 40° deep single thread provides a secure fixing with high pull-out resistance. A single slash on 25mm+ screws reduces torque and prevents timber splitting when inserting close to the edge.

All screws up to 75mm in length are fully threaded, while those 80mm and above have a 70mm thread length for optimal grip and stability.

Key Features:

• Marine-grade A4 stainless steel construction for corrosion resistance
• Double countersunk head for reduced head shear and flush finishing
• 40° deep single thread for secure fixings with high pull-out resistance
• 25° sharp point for easy insertion
• Compatible with PZ1 driver bits

These screws are ideal for use in green oak or other corrosive environments, ensuring long-lasting durability and performance.
