COUNTERSUNK SCREW FOR HARDWOODS HARDWOOD CERTIFICATION Special tip with diamond geometry and notched, serrated thread. ETA-11/0030 certification for use with high density timber without any pre-drill. Approved for structural applications subject to stresses in any direction vs. the grain (α = 0° - 90°). LARGER DIAMETER Inner tip diameter increased to ensure tightening in the highest density woods. Excellent twisting moment values. HBS H Ø6 mm, comparable to a diameter of 7 mm; HBS H Ø8 mm, comparable to a diameter of 9 mm. 60° COUNTERSUNK HEAD Concealed head, 60°, for effective, minimally invasive insertion, even in high density woods. CHARACTERISTICS FOCUS hardwood screw 60° taper with under-head ribs MATERIAL Galvanized carbon steel. timber based panels solid timber and glulam CLT, LVL high density woods beech, oak, cypress, ash, eucalyptus, bamboo Service classes 1 and 2.

HARDWOOD PERFORMANCE Geometry developed for high performance and use without pre-drilling on structural woods such as beech, oak, cypress, ash, eucalyptus, bamboo. BEECH LVL Values also tested, certified and calculated for high density woods such as beechwood Microllam® LVL. Certified for use without pre-drilling, for densities of up to 800 kg/m3.
