DSPROA4

Hardwood Decking Screw - Stainless Steel A4

The DSPROA4 hardwood decking screw is a powerful fastening solution for hardwood decking such as IPE, Cumaru, Bankirai and others. Made from A4 stainless steel allows for the screw to be used in marine environments. The screw is designed to resist movement of the deck with a trim head for a neat, professional finish. The additional second thread helps pull the deck boards to the joist providing a more secure clamping effect.
Recommend pre-drilling with 4.0mm drill bit and pre countersinking close to the edge.
