Also known as Surefix, CSK or Superscrews - these square drive self tapping and countersinking wood screws are a construction and handyman staple.

Ideal for round the house projects and fixing sheet materials to walls and floors.

You'd be crazy not to have a handful of the various sizes in your tool kit at all times.

Our Square Drive Superscrews are highest spec hardened steel with a European market compliant ROHS silver zinc coating.
