4.5x30 Classic Multi-Purpose Screws PZ Double Countersunk Stainless Steel. Box of 200

Ideal where ultimate corrosion resistance is required when fixing to softwoods, hardwood (pre-drilled), chipboard, MDF and plastic. Stainless steel must be used where there is corrosive environment and/or the base material has inherent corrosive characteristics e.g. Green Oak.

• Double countersunk reduces the likelihood of head shear and assists completion of countersinking
• 40° deep single thread to provide a secure fixing with high pull-out resistance
• Single slash on 25mm+ to reduce torque and the likelihood of the timber splitting when the screw is inserted close to the edge
