Description
Drillex®
White Zinc plated
TC PH
Self-drilling and self-tapping screw for screwing directly into sheet metal and metal laminates without a pilot hole.
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.
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

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.
