DIN: 7504N
Fej: pan
Surface treatment: zinc plated
Self-drilling Linsenkopf metal-sheet screws in compliance with DIN 7504. Linsenkopf self-drilling metal-sheet screws are used for fixing two metal sheets. Due to the design of the screw head the surface pressure decreases during the tightening, thus the head does not perforate so the Linsenkopf self-drilling metal-sheet screw is ideal to fix thin sheets. The extent of thickness in which the material can be perforable must be not more than 3 mm. Due to the bit, the working process is shortened. Linsenkopf self-drilling metal-sheet screws have PH groove and galvanised. It is also known as self-tapping metal-sheet screw
