TIMCO Classic 4.0 x 25 Multi-Purpose Countersunk A2 Stainless Steel Woodcrews (Box of 200)

All the features and superior performance of the Classic Multi-Purpose Screw manufactured from A2 Stainless Steel. 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.
All sizes up to and including 75mm are fully threaded and lengths 80mm and above all have 70mm thread length
