SCREW-TITE® ZINC 3.5 x 20mm Pz Countersunk Screw (Box of 200)

    Description

    Works in almost anything, without the need to pilot.

    Screw-Tite® is our multi-purpose screw, designed for load bearing, structural applications.   It works in the majority of materials and without the need to pilot and is proven to outperform competitors’ brands thanks to its unique Tri-Lock threadform, offering the user a screw that is 30% faster and 25% stronger than other market leading names.  

    SCREW-TITE® BENEFITS:

    §  CLEAN, FLUSH FINISH – SELF-COUNTERSINKING

    Underhead ribs self-countersink, whilst a double collar provides extra strength.

    §  NO MORE JACKING APART OF THE MATERIALS

    Partial thread prevents jacking & provides exceptional clamping.

    §  30% FASTER - TRI-LOCK™️ THREAD.

    Unique trilobular thread provides fast insertion, reduced friction drive & a locked fix.

    §  25% STRONGER – NO MORE PILOT HOLES.

    As strong as a HT bolt, the screw should not snap & there’s no need to pilot in most materials.

    §  2 THREADS, 1 SCREW – TS THREAD SYSTEM

    §  TWIN THREAD TIP offers an immediate start with a balanced drive.

    §  SINGLE COARSE THREAD drives easily without reaming for a fast, solid fix with high pull out retention.
