Silver zinc plated wood screws, perfect for plugs and wall fixings. Exceptionally popular in construction as they have deep sharp threads that cut into the wood rather than simply forcing their way through, plus a penetrating tip requiring no pilot hole or pre-drilling. These screws are heat treated to ensure they are hard and resistant to snapping. For use in soft or hard wood, MDF or chipboard. Precision Pozi-drive head. Boxes of 200.
