Description
Self-drilling and self-tapping screw particularly indicated for fixing: cable ducts, omega bars, thin wooden or plastic panels to metal structures, plasterboard wall linings frames, light structures, prefabricated sheet metal structures.
RECESS
deep to ensure secure matching with the screwdriver. A deep recess, of a perfect shape, enables he same insert to be used for thousands of screwing operations.
LARGE FLANGED HEAD
which eliminates the need for washers.
THREAD
up to below the head, to allow the gripping of extremely thin sheets.
TIP
DRILLEX® self-drilling tip, which can penetrate thicknesses of up to 5 mm, threading and tightening consecutively.
CARBONITRIDING HEAT TREATMENT

GALVANIC TREATMENT
The 100hrs white zinc plating treatment guarantees a rust resistance a third higher than that of standard galvanizing. Complies with the EN1670 standard grade 3.

IN PROCESS CONTROLS
The entire manufacturing process is subjected to SPC (Statistical Product Control), which guarantees a constantly high level of quality in time.
The batch number on the labels ensures absolute traceability of all the phases of production and related control/test documents.
DRILLING TEST
all batches are tested with special instruments to determine their drilling rate in the various materials.
- The large flanged head of the Drillex® FFLL screws eliminates the need for washers.
- The characteristic self-drilling tip of the Drillex® screw, which enables an optimum drilling diameter to be obtained, threading and tightening consecutively up to a thickness of 5 mm.
- Drillex® self-drilling tip: section of the screw that shows the characteristics of the carbonitriding treatment.
- The graph comparing a Drillex® screw with a traditional screw that shows that the SPC process improves the average production quality and, at the same time, the tolerance.
