The ideal discreet lost head screw for skirting, carcases and tongue & groove flooring. Removable & hidden. Suitable for hardwood, softwood, fibre board, engineered and modified timber. No pilot hole necessary in most applications. Removable unlike nails, pins & glue. Free driver bit in every box. These Lost-Tite screws provide an easy fix for tongue and groove cladding or flooring. The lost head ensures a semi-concealed and flush fit, with none of the hassles you'd get using messy glues, nails or panel pins. The screw heads feature an ST10 star recess, giving you greater grip and excellent control. An extra thread eliminates screw extrusion if the timber shrinks, and the screws are easily removable too.
