AnchorMark TTM 6.3mm Self Drilling Screw +++NEW+++

Fixing timber panels to metal substructures: up to 8 mm steel.

Our TTM Timber to Metal Screws are the perfect fastener to fix timber to metal under-constructions without pre-drilling. Perfect for industrial use.

The advantages of these screw are:

  • Self drilling screw with SIT Drive (up to 8mm steel).
  • Ruspert coating for excellent corrosion protection.

1) The SIT® drive (TX compatible) allows for optimum torque transmission, a tight and snug fit, and fast centering. The large flat washer head offers greater tightening force (even in warped boards) and increased pull through resistance than a countersunk or small hex head fixing.

2) The high efficiency thread with RUSPERT coating reduce the frictional resistance when screwing in and provides excellent corrosion protection.

3) The cutting points of the self drilling thread allows for an immediate screw start coating to reduce drive-in torque after the metal grip.

4) An aggressive drilling tip with wings cuts a clearance hole for decks with a steel under construction. It allows quick, easy and safe work without pre-drilling for steel thickness: 3.0 – 8.0 mm.

The screws with an additional RUSPERT® coating gives them a high corrosion and weather resistance, increased fracture torque, and makes them suitable for gardening, landscaping, and wood constructions.

RUSPERT® ( Patent No 1526310 and 1570203)

The amazing metal finish is a high-grade metal surface processing technology that prevents corrosion. It consists of three layers: the 1st layer: a metallic zinc layer, the 2nd layer: a high-grade anticorrosion chemical conversion film, and a 3rd outer layer; baked ceramic surface coating. The distinguishing feature of RUSPERT® is the tight joining of the baked ceramic surface coating and the chemical conversion film. These layers are bonded together through chemical reactions, and this unique method of combining layers results in rigid combination of the coating films. RUSPERT® treatment does not attribute its anti-corrosion properties to merely a single material, but the synergy of these three layers, which combined have superb rustproof qualities.
