Fastshifter Invisible C4 screws are designed for fixing decking, floorboards and other outdoor timber structures. This pack contains 600 brown 4.5×60 mm screws with a TX15 drive and a matching bit.

Discreet fastening

The double thread helps draw boards together, while the conical head is designed for a finish without visible screw heads. The drilling tip helps reduce splintering and splitting of the wood.

For outdoor timber

Suitable for both standard and thermally modified wood, the screws are made from galvanised carbon steel. They have a C4 corrosion resistance class and have passed a 1680-hour salt spray test. They resist moisture and temperature changes.
