3.5 x 49mm Tongue-Tite® Plus Tx Countersunk Screw, Black Stainless (200)

    Description

    A specialist screw designed for use in the installation of softwood, hardwood and fibre tongue & groove floorboards.

    With the Tri-Lock TS thread, the screw will drive straight through the board and into the substrate without the need for a pilot, even in hardwood, whilst the single coarse thread is designed to eliminate ream out of the floorboard, giving a high pull out retention.  In other words, no more squeaky screws. The small head provides a neat, hidden fix and unlike messy glues and nails, the screws can easily be removed when needed.

    Tongue-Tite® Plus is our 305 stainless-steel version with all the benefits of Tongue-Tite® but with the advantage of protection against corrosion making it suitable for exterior use or in damp environments. Tongue-Tite® Plus is awarded the TDCA CladMark®+ accreditation.

    TONGUE-TITE® BENEFITS:

    • THE ORIGINAL AND STILL THE BEST.
    The easy and removable fix for tongue and groove boards.

    • ALMOST HIDDEN FINISH – SMALL DISCREEET HEAD.
    Fixes flush allowing the next board into place with tongue & groove applications or for an almost hidden, face fixed finish.

    • NO NAILS, NO GLUE, NO MORE MESS.
    A simple, clean installation that unlike messy glues and nails, can be unscrewed for access or repair.

    • TRI-LOCK THREAD FOR A SOLID FIX.
    Unique, trilobular thread provides fast insertion, reduced friction and a locked fix, ensuring the boards stay in place.

    • HIGH CORE STRENGTH HELPS PREVENT SNAPPING.
    Specifically developed so the screw will not break as the boards flex under use.

    • 2 THREADS, 1 SCREW – TS THREAD SYSTEM.
    1. TWIN THREAD TIP breaks the dense surface of the board without damage with an immediate start.
    2. SINGLE COARSE THREAD eliminates reaming of the boards and offers a high pull out retention.

        Screw-Tite® > Drives fast. Holds tight. Job done.

        • No pilot hole needed (most of the time)
          Screw-Tite screws are designed with self-drilling or self-cutting tips, meaning they bite straight into wood and many materials without pre-drilling.
          Less prep, fewer tools, faster jobs.
        • Advanced thread design = stronger hold
          They often feature deep, sharp threads that pull materials together tightly and reduce splitting.
          Result: a more secure fix with less effort and fewer stripped holes.
        • Precision drive head reduces cam-out
          Screw-Tite screws are typically designed with high-quality drive recesses (like Pozi or Torx-style) that give better bit grip and reduce slipping.
          That means fewer stripped heads, cleaner installs, and less swearing mid-job
